Apparently I cannot use this device without paying one time activation fee despite the device being already active for the trial week and then a monthly subscription. Had I known this, I would not have purchased. I almost did the monthly but they were not willing to honor the coupon code from their own website and when I asked why they wouldn’t I got a reply “sorry, we don’t have any value to offer you.” Stay away. I wasted $94 buying a “brand new” device off ebay. I had no intention of using their subscription feature or “insights” and meal plans so I figured I’d buy unopened from another seller since that option is not available from Lumen directly.
Hi Nicole, Thank you for your review, and we apologize for this experience. When you first start using the Lumen device, you will have access to the Lumen app for about a week. After that, you’ll be prompted to enter a membership activation code in order to continue using the device. When a device is purchased directly from us, the activation code is included as part of the original purchase. Lumen devices purchased second-hand from third-party sellers (such as eBay) should include an activation code provided by the seller. If it was not provided by the seller, an alternative option would be to purchase one directly from us. Please note that each membership activation code can only be redeemed once. Regarding the coupon codes, they may not always apply due to specific terms. However, we’re happy to work with you on this. Unfortunately, we cannot locate your contact details using the information provided on TrustPilot. We have submitted a request for your information and look forward to getting you up and running with your Lumen. All the best, The Lumen Team
Worst experience ever. I bought 2. One for me and one for my mom. They both stopped working and cannot be turned on. Customer support is terrible one on one. The only time they respond is to not look bad. Would not believe a word they say or waste my time with this type of company.
Hi Sheila, Thank you for your review, and we apologize for this experience. We’re sorry to hear that your experience with our support team has been disappointing. That’s not the level of service we aim to provide. Your feedback is important to us, and we would truly appreciate the opportunity to make this right. Unfortunately, we cannot locate your contact details using the information provided on TrustPilot. We have submitted a request for your information and look forward to speaking with you to get your Lumen devices back up and running. All the best, The Lumen Team
The Lumen app has helpful information however, I keep forgetting use it. The reason I cam giving them only 4 stars is I received email notification that my Lumen was being renewed on 04/17/2026. I much appreciate it however, I want to cancel it. I deleted account on app today and haven received email confirmation from Lumen. When I saw this I also Deleted account on their web site. Still no confirmation email or sorry to see you go emails. :-0) If Lumen representative receives this message be advised if I am charged a renewal fee it will be reported to my bank as fraud. I'm surprised Lumen doesn't have auto responder for these type of requests. Karen ---------- Update, changed rating from 4-1. Customer Support and Customer Service does not communicate well with each other. As a result. I was charged $159.00 today rather than on what was supposed to be 4-17-26. Also, Customer Service emailed me earlier today and talked me into keeping Lumen and only paying $80.00 renewal fee. Tonight they billed me the full $159.00. I emailed them tonight and asked for a full refund and confirmation email that I would not be charged $80.00 to renew on 4/17/2026. I also want to delete/deactivate my account. It's I've wasted enough time and too much confusion due to their poor customer service and support. Updates to follow.
Hi Karen, Thank you for your message, and we apologize for this experience. To clarify, deleting your Lumen profile is not the same as canceling your membership. To stop renewal billing, the membership must be canceled either within the Lumen app or by contacting support. Once the cancellation is completed, a confirmation email is automatically sent. That said, this is not the experience we want for our customers, and we apologize for the lack of clarity and consistency in communication. Unfortunately, we cannot locate your contact details using the information provided on TrustPilot. We have submitted a request for your information and look forward to speaking with you regarding the membership charge and offer. All the best, The Lumen Team
Last year I have bought the Lumen Pro, the “new version”. This company said it was pre-ordered, that the new device was going to be ready to ship 1st quarter this year. I haven’t received the device, I have sent emails and NO answer back and now I see they no longer advertise or have it for sale.
Hi Laura, Thank you for taking the time to share your feedback! We weren’t able to locate any previous support inquiries linked to your account regarding the Lumen Pro. That said, we absolutely want to look into this for you and help resolve it. The Lumen Pro was offered during a pre-sale phase and has not yet been released to the general public, which is why it is no longer being actively advertised at this time. Our support team is going to reach out to you directly to review your order and assist you. All the best, The Lumen Team
It helps me plan food choice's and helps me when fasting good products
Hi Jason, Thanks for the 5-star review! We're glad to hear Lumen has been helpful in meal planning and fasting. Keep up the great work! All the best, The Lumen Team
Great tool to live a healthy lifestyle and track my metabolism. This has helped me tremendously with my metrics and shed few pounds. There’s a little bit of a learning curve but plenty of resources from the other users in the community and in the app. The food tracking in the app is basic and I barely use it because of its limitation; overall I will buy this device again and I will recommend it to friends and family.
Hi Karim, Thanks so much for your 5-star review! We’re glad to hear the tool has helped you make progress and better understand your metrics. We appreciate your feedback on the food tracking as well; we’re always working to improve those areas. Keep up the great work! All the best, The Lumen Team
