Many consumers point out that the customer support team is responsive, friendly, and genuinely helpful when assistance or replacement parts are required.

The rest pad that I purchased was great, comfortable to rest on and not too high for my palm.
Thank you for the great feedback! We designed our rest pads to offer the perfect ergonomic height for long sessions, while seamlessly matching the sci-fi aesthetics of the rest of our lineup. We're glad it fits right into your Gravastar setup!
The customer support experience been amazing. I contacted them becasue chosen the wrong color of a mouse. 🤯🤯🤯🤯 The wrong mouse which has been already taken by post. Support got back old order and replaced it with right one!!!!!!! This is some level of Steam Support experience. WP. GravaStar
Haha, comparing us to Steam Support is the ultimate compliment! Thank you so much! Our logistics and support teams always try their absolute best to intercept and fix these little mishaps whenever possible. We are so glad we caught it in time and got the perfect color into your hands. Enjoy your new mouse! WP indeed!
i spent 200 dam dollars on this peice of shit keyboard and its battery life is shit it also looks like shit not to mention it has a delay in the keys it sounds nice thats about it
Thank you for sharing your feedback, and we are truly sorry to hear that your experience with our keyboard has not met your expectations. A noticeable key delay and poor battery life are definitely not the standards we aim for. These issues can sometimes be related to connection modes (such as 2.4GHz wireless vs. Bluetooth), RGB lights, or needing a firmware update. We want to make this right for you. Could you please reach out to our dedicated support team at [email protected]? Please include your order details, and our team will gladly help you troubleshoot the technical issues or arrange a replacement/solution for you if the unit is defective.
Really fast customer service and super helpful!
Thank you for taking the time to share your positive experience! Providing fast, helpful, and friendly support is a top priority for us, and we're glad we could assist you quickly. Thanks for your amazing support!
Had my Mars pro for three years won't charge or turn on apparently they don't keep parts for repair, according to Reddit it's been a known issue for years.... Hundreds of people have had the same problem, and had the same response, some people only after a couple of months..... It's now a very expensive paperweight..... Edit... Google Gravastar mars pro problems Reddit.... There are thread after thread.....and the first issues appeared 4 years ago, yet nothing was done until the mk2... I have to say the biggest complaint is customer service and aftercare..... Google it....
Thank you for sharing your feedback, and we are sorry to hear about the issue with your Mars Pro. We would like to clarify that GravaStar offers a standard 1-year warranty on our products. If any issue occurs within this period and cannot be repaired, we always provide a brand-new replacement free of charge. We take customer service very seriously, and the claim that "hundreds of people have had the same issue with no support" does not accurately reflect our after-sales commitment. Regarding your specific speaker, since it was purchased 3 years ago, this particular original model has been discontinued, which is why individual repair parts are no longer available. However, we have since launched the upgraded Mars Pro V2, which features significant improvements in both hardware and performance. Even though your product is well outside the warranty period, we value you as an early supporter. Please feel free to reach out to our team at [email protected] with your original order details, and we would be happy to see how we can assist you or offer a special discount on our latest upgraded models.
it was awesome, all they’re stuff is sick and the agent really helped me
Thank you so much for the awesome review! We're thrilled to hear that our customer support agent was able to help you out, and we love that you think our gear is "sick"! Bringing that sci-fi, cyberpunk vibe to your setup is exactly what we aim for. Thanks for rolling with GravaStar!
Absolutely the best keyboard and gaming products I’ve ever had. I highly recommend all of their products
Thank you so much for the 5-star review! We're thrilled to hear that you're happy with your experience and our gear. Thank you for being a valued part of the GravaStar family, and enjoy your new setup!
I bought earbuds in December of this year, and they started having some problems to the point where I could not use them anymore, I contacted customer service and got an answer quickly. I am grateful for their reactivity and attention to the problem; responses to my messages never took more than a day. I love those earbuds, they are lightweight as well as pretty, and the noise cancelling they provide is a godsent for someone who gets overstimulated quickly. Thanks again to the Gravastar team.
Thank you so much for sharing your wonderful experience! We are incredibly happy to hear that our customer service team was able to support you quickly and efficiently. It warms our hearts to know that the lightweight design, aesthetics, and especially the active noise-canceling feature have been such a helpful "godsend" for you. Providing comfort and a peaceful sanctuary through our gear is exactly what we strive for. Thank you for being a part of the GravaStar family! Best regards,

Hello I am writing this review because I have tried dealing with Gravastar's customer service. I purchase Christmas gifts throughout the year. Around this time last year (June), I purchased two Mercury X Pro mice as gifts. I gave one to my son and one to my daughter as presents. My daughter used her mouse maybe 8 hours total, and the scroll wheel broke off, making the unit unusable. I sent pictures and a short video, and all I got was the runaround. They said it's past the one-year warranty, so they are not obligated to replace it. Now I have purchased over $2000 of their products, Speakers, docking stations, and chargers, all as gifts to my young adults and clients of mine. We had issues with the docking stations recharging in the past; they sent a fix, and it worked fine. Now they've got me taking apart the mouse and sending pics of the inside. It's clearly a manufacturer's defect. I have had mice for years without any issues. They even admit they have seen this issue before. Now all I get is the runaround. I won't be purchasing anything from this company again. They have cool stuff, but it just doesn't work properly. Now I am out $130.00 because it's over a year. It sat in my house for 6 months before I gave it as a Christmas gift. In the pics I sent, it looks brand new. Update:06/18/2026 Here is the email Gravastar sent me yesterday morning. They seem more concerned with the review than with the problem at hand. "Where did you send the package back? We did not provide the return address previously. We must declare that address confirmation is not another tactic for delaying and denying claims. It is necessary step for all of the after-sales process. We will send the new package to you today at the following address: And we received a notification today that you left a 1-star comment on Trustpilot. Could you please remove or revise the comment"? I provided them with my tracking information when I sent the defective mouse back to them without their authorization. I sent it back to the warehouse it came from. I want them to physically see that the mouse was brand new and had fewer than 8 hours of use. They did not provide any tracking information yet. I feel confident they will. But why would you ask me to remove the post on Trustpilot? As a businessman myself, if this ever happened to me, I would make sure the client was happy with the final outcome before ever asking for an edit to a complaint post. I will keep Trustpilot updated if I receive a new mouse and if it works as it should. Updated 06-18-2026 2nd post Here is their latest response I received early this morning. I actually don't believe they have an engineering and quality control team based in a warehouse in Henderson, Nevada, and they are going to look at this on Saturday when it arrives. But the good news is they are sending a new one as they should. We will see. Here is the email below, more AI BS. "Thank you for your reply, and I sincerely appreciate you sharing the return tracking details and address with us. First and foremost, I want to extend our most sincere apologies for how the previous communications made you feel. It was never our intention to sound dismissive or to show a lack of empathy, especially knowing that this was a special Christmas gift for your children. We truly value you as a loyal customer who has supported GravaStar over the years, and we take your feedback about our customer service tone very seriously. We will absolutely use this experience to do some internal soul-searching and improve our support training. We want to make things right for you immediately. Your replacement package has indeed been dispatched, and here is your official tracking information to monitor the shipment: • Carrier/Logistics Provider: Cirro • Tracking Link: Regarding the mouse you sent back to our Henderson, NV warehouse, please rest assured that we will not throw it in the trash. Our engineering and quality control teams will personally inspect it as soon as it arrives this Saturday. Your feedback about the scroll wheel issue is crucial to us, and examining your device will help us identify potential manufacturing or component vulnerabilities so we can prevent this from happening in future batches. We are fully committed to ensuring your children can enjoy their gear smoothly. Once the new package arrives and you have had a chance to verify everything is in perfect, brand-new condition, would you be open to re-evaluating your experience or updating your comment on Trustpilot? Your satisfaction means the world to us. Thank you again for your patience, your constructive criticism, and for giving us the opportunity to correct this for you. 06/24/2026. I would like to thank Gravastar for sending a new Mercury mouse. Received it yesterday and works just fine.
Thank you for sharing your feedback, and we sincerely apologize for the frustration this experience has caused you and your family. We completely understand how disappointing it is to encounter an issue with a gift, and we deeply value your incredible loyalty as a customer who has purchased over $2,000 of our products. While the 1-year warranty period had indeed passed, we want to reassure you that our goal is always to make things right. As our customer service team recently communicated to you, we have already approved a free replacement solution for your daughter's Mercury X Pro mouse to resolve this manufacturer defect. We apologize if the previous troubleshooting steps and requests for internal photos felt like a "runaround"—our technical team uses these details to improve future product designs, but we realize it caused unnecessary hassle for you. Your replacement is being handled with priority. If you have any further questions or haven't received the updated tracking details yet, please feel free to reach out to us directly at [email protected]. Thank you again for your patience and for helping us improve. Best regards,

150 euros for a keyboard that is garbage, the software that they recommend to use basically bricks the keyboards, and customer support doesnt help. The usb dongle is also laggy making wireless connections difficult

Please kindly reach out to our customer service team at [email protected]. Our team will guide you step-by-step to see if the issue can be resolved.

The support team was incredibly helpful. They walked me through everything step by step, and it finally works perfectly! I really appreciate their patience and great support. Highly recommended!
Great product and professional service. Fast delivery
This is regarding Order #GR96476 Issues with 4k polling dongle which disconnects after 5 seconds of use rendering the wireless feature completely useless. After chatting with them via their site and customer email we ran through all the diagnostics and was made to pay $10 to get a new dongle shipped, was told it was being shipped the same day i paid the $10. A month later no dongle so i reached back out to them and was told that the dongle will be shipped after providing the SN... So a whole month and nothing was being done. and the countless emails before hand they couldnt ask for the SN??? Ive been using the mouse wired (M1) for the last month which is terrible for gaming. Im really disappointed in these guys and would love to say the products are good but after all of this it has left a bad taste in my mouth about Gravastar as a whole.
Thank you for getting back to us. We sincerely apologize for any confusion caused during this process. To explain further, our support team requested the Serial Number (SN) because it is required to properly pair and configure a new 4K dongle with your specific keyboard before shipment. We want to ensure that the replacement works perfectly for you right out of the box. Our customer service team has sent another email to you regarding this. Since you mentioned communication issues, please check your Spam/Junk folder for a message from [email protected]. You can also reply to us here on Trustpilot with your SN code, and we will expedite the shipment of your new dongle immediately. Thank you for your understanding and cooperation!
I initially wanted to buy a keyboard to go with my mouse. I came across one with a very unique look and decided to pay a premium price for it, but I later felt the quality didn't justify the cost at all—it was grossly overpriced. I do not recommend it!
Dear Kloe, Thank you for getting back to us. We want to assure you that our customer service team has already reached out and replied to your emails!

Please kindly check those folders for an email from [email protected]. To ensure you get our messages moving forward, please consider adding our email to your whitelist. In the meantime, our dedicated support representative will try to contact you again right away. If you still see nothing in your inbox, please feel free to send us a direct message here on Trustpilot with an alternative email address or contact method, and we will get this sorted out for you immediately.
