Mercury X Pro Mouse Battery Defect, and Gravastar has the worst customer support I've ever seen
The Gravastar MercuryX Pro mouse that I ordered has a defective battery and will not charge.
I contacted customer support, but they refuse to replace the product. They are only asking me to make videos that have nothing to do with the defect.
It seems as if they are just buying time or hoping I'll give up and keep the defective product.
This is the first and last time I will order from Gravastar.
It is the worst service I have ever experienced with a defective product.

The keyboard I bought will not work…
The keyboard I bought will not work with my system, due to Gameinput service shutting my PC down. I contacted support and tried what they suggested, still doesn't work. I asked for a refund, Instead of having somewhat decent customer service and giving me a refund they want me to go through all the steps they suggested again and film it. The keyboard is great, their customer service is horrible!
Update 9/8
So they asked me to contact them again to try and make it right. After about 6 emails back and forth they want me to do the same thing for a 4th time and make a video before they will do anything. DO NOT BUY from this company.

This company strings you along for a week before it takes care of anything still hasn't taken care of anything. Trying to get a return label in return, a mouse that hasn't been opened. I took a picture of it and showed them the labels were not broke and they said, oh, it looked like it's been open. Did you use it? I said, no still waiting on the label. This company's customer service Is the worst ever do not buy from this company

The products have a nice design and the quality is more than good, but the QC is bad and the service is even worse. He almost never responds, and if he does, it is useless and only after he insists. In any case, it's a disposable male.

Gravastar Mars speakers consistant connection issues since purchase
I have two gravastar mars speakers and they both function poorly. I keep them fully charged and are located within three feet of my pc tower, and yet they consistently cut out and disconnect from from blue tooth. My PC is only 16 months out so i dont believe that the issue is there as they had connection issues on my previous laptop. For the amount you pay for these speakers, there shouldnt be this many issues.

While it sounds like you've already tried different setups, we'd love the opportunity to investigate this further and make things right. If you haven’t already, please reach out to us at [email protected] with a short video of the issue and let us know whether you’re using stereo pairing or single speaker mode.
We’re committed to standing by our products and our customers, and we’ll do everything we can to resolve this quickly for you.

Dear Earl,
We’re truly sorry for the condition in which your package arrived and the experience you've had with our support so far. That’s absolutely not the level of service we aim to provide, and we understand how upsetting it must be to receive a damaged box—especially with part of your order missing.
While our warehouse team ensures each product is carefully packed before shipment, we acknowledge that things can go wrong during transit, and we should have handled your concern with more care and urgency.
Please allow us the chance to make this right. If you could kindly resend any photos of the packaging and its contents, we’ll escalate this to our logistics and customer support team immediately and work on a proper resolution—whether that’s a replacement or refund.
We’re committed to earning back your trust and sincerely apologize for the frustration this has caused.
Best regards,
GravaStar Team

Extremely long delivery time & unresponsive support
I placed an order with Gravastar on February 15th for approximately €1,500. Since then, I have been waiting for my order to arrive. Only minor, non-essential parts, such as the wrist rest and keycap remover, were delivered five days later via Amazon. However, these items were clearly returns, although their condition was acceptable – so far, so good.
However, all the essential items, such as the keyboard and mouse, are still missing. There have been no further updates, and when attempting to contact support, they refuse to open a ticket related to the shipping issue.
I had high expectations and a positive impression of this company, but once again, I have been disappointed by an unprofessional and unreliable business. A waiting time of over two weeks without any communication is completely unacceptable and disrespectful.
This was my last order with Gravastar, and if my items do not arrive by next week, I will request a cancellation and demand a full refund.

HORRIBLE customer service
Tried to return earbuds because they don't handle high volumes well and pop like weak speakers when turned up, sent an email to request a return, they didn't respond for 2 weeks, then didn't even reply to the email just gave me a troubleshooting faq, I said no I want a return, they took another week to respond saying I had to pay for shipping, I agreed then they send me a email say it exceeded then 7 day limit which was entirely their fault, and who has a 7 day return policy for electronics especially when you're an online company shipping your product. Horrible experience with this company, will never in a million years do business with them again.

Hi Gregory,
Thank you for taking the time to share your experience, and I’m truly sorry to hear about the frustration you’ve gone through. This is not the level of service we aim to provide, and I completely understand how disappointing this must have been for you—especially with the delays in our response and the confusion around the return process.
I’d like to make this right. It’s clear we dropped the ball here, and the delays on our end should not have impacted your ability to return the earbuds. I’ve gone ahead and escalated this to our team, and I’d like to offer you a full return, since the timing issue was on us. If you’re open to it, I’d also be happy to send you a replacement pair or provide a discount on a future purchase to show our commitment to turning this around for you.
Could you please send me a quick message with your order number (either here or to [email protected])? I’ll personally oversee this to ensure it’s resolved quickly and to your satisfaction. We really value your feedback—it’s how we improve—and I hope we can regain your trust.
Looking forward to hearing from you,
Best,
GravaStar Team
