Starting to wonder about this company. Ordered directly from mars hydro website to avoid this. Money come right off card and days go by no shipping confirmation. Contact them and finally get response that zip code was wrong. Ok, I have resent zip code and politely asked for update on shipping. That has been another week no response. Needed product sooner then this and website said next day shipping from USA. No replies to emails. Really wish I spent the extra and bought one locally.
Awful lamp.
Received it , lamp keep producing light when the time is off, been waiting 2 month for mars hydro to send a replacement driver.... they keep telling me it will be sent but don't say when....
Guess I can throw that 140euro lamp to the garbage
Ordered a light with them via amazon (UK).. Order got cancelled.
Ordered with them via ebay (UK).. They said the item was posted and 10 days later they cancelled it saying that their courier don't deliver to Channel Islands (UK).
Then I ordered on their website, emailed them and put a note on the order saying that I could pay extra for shipping.. Took them 2 weeks to say that I'd have to pay 100USD for shipping from China, even tho they have a warehouse in the UK.
Really bad costumer service, don't reply to emails.. Felt ignored. Really unprofessional.
Bought ts1000, dim function does not work, i get shocks wherever i touch the device, even the hanging wires. Submitted ticket to helpdesk service and sales, 2 week past since first message, getting no response at all.
I ordered the ts600 light and a 70 70 160 grow tent they refunded me for the tent because they had none in stock they didn't have no mention on this from the website if I new that I would have ordered of amazon well I have Been back and forward with emails witch may I add that they take 3 to 7 days per email to get a response after trying to get aa tracking number from them for just the light they informed they was out of stock till the 25th Jun 2020 it is now the 29 Jun 2020 end they have emailed me saying we are sorry we have sent you a refund because all though we had the item in stock wee have ran out again aandd have missed you out they sent a refund wouldn't deal with this company they are a complete waste of your time mars if your reading this I had rally good hopes of your product and as a new customer I would of expected a lot better customer service and the fact the messing about
This company has zero customer service. They do not respond to phone calls, emails, or via the contact us section on their website. I purchased a tent from them and needed to return it. I could not get any response from them, so I returned the item to the US address on their website using UPS with signature confirmation. They received the item and signed for it, but are denying they received it. I still have yet to get any call or email back from the company after over a month. I will update my review if my issue is resolved.
company are absolutely useless sent them two tickets or messages whichever you want to call it don't bother replying I certainly won't be buying any of their goods anymore more. And that includes spider farmer.
Finally got a reply after about a week and a half
Had one of their units have individual led’s go out. I ended up giving up trying to get them to tell me which parts I needed.
Their procedure for warranty or repairs is well documented on their website. They gave me a totally wrong answer as to what parts were needed, as if the tech was looking at someone else’s photos and email. They would not respond to questions, just wanted me to send them money.
I started the process over with a different support person. I had to pull teeth for any response at all, and then they just stopped responding completely. Pretty weird.
I would give zero stars if I could.
Definitely not recommended - Very unprofessional company!!!
Extremely bad customer services.
Delaying answering to my emails and never answer my calls.
They really made me feel that I was scammed.
First time I faced, these kind of unprofessionals. After paying them, they sent me an email requesting me additional $50 for delivery (even if they were advertising free intentional delivery).
I paid them and I requested tracking number for my order. However, they were giving me excuses that tracking numbers 'does not come up'. They assured me that the delivery time would have been 3-5 days, which at the end was proved that was a big lie.
They were giving me also excuses that they run out of stock from Germany and then that Amazon delays to dispatch my products, even if I purchased directly from their website. I had nothing to do with Amazon. Since my order wasn't dispatched, I requested cancellation and they have rejected as suddenly they were giving excuses that the products were 'dispatched'.
After a very long time and a lot of emails, I received only 1 of the products I ordered.
I sent them an email and they told me 'Amazon has cancelled my order', without justifying order's cancellation reasons.
Their product reviews seemed to be good but in terms of customer service are below zero. This is big shame as nowadays, customer care matters a lot.
Definitely not recommended.
I will not purchase anything from them again.
P.S: All emails and screenshots proofs can be provided if requested.
