So today’s 3/2/25, I’ve been using my speaker for 3 months now. An accidental fall in the pool and a fall out of a moving car and somehow this speaker still hecking works? Like they don’t say anything about water resistance but my speaker sank to the bottom of my pool, It had time at the bottom of my pool while I was taking off all my clothes to jump in the deep end to grab it and I pulled it out of water, shook it off and somehow it still out of sheer dumb luck turned on and played music. I’ve abused the shit out of this speaker in my work’s dish pit jamming spraying water everywhere and it still somehow works. Like yeah over $100 for a speaker is a lot but honestly the metal construction, careful attention to detail and the just sheer sound quality made every cent worth it. Tbh I was stupid to buy the supernova, now I’m gonna have to get a Mars Pro and all sorts of stuff so I’m gonna have to bury my next few paycheques.

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. ORDER #GR67433

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

I ordered a Mercury K1 Pro Special Edition Galaxy Black keyboard and a Mercury X Pro 8K Wireless Gaming Mouse. Neither the keyboard or mouse match up in color. The keyboard is more of a gun metal gray while the mouse is black. I have sent photos to customer service and they proceeded to tell me that they sent me the right keyboard. This is clearly wrong as you can see in the photos. I just want to return this keyboard and receive the one I paid for. Customer service skills and response times are the worst I’ve experienced in a company so far. Just send us what we paid for or when you make a mistake just remedy the situation. Update: 2/20/25 Over a dozen emails back and forth later and still no resolve. Nowhere in the website description does it say that a galaxy black keyboard and a galaxy black mouse are different in completely different in color. This product is purely for aesthetics yet your same color I have asked to return the unused product for a refund and have been refused several times. Gravastar has misrepresented the product they sell and customer service has been substandard. I would suggest gravastar works on better customer service skills and updates the name of their galaxy black from keyboard to mouse colors since they do not match. I would suggest when a customer is not satisfied with your misrepresented colors schemes or product in general and have not used it, tell them to return your product and issue a full refund. Do not continue to sand bag your customers. Also update your pictures on your website to reflect the actual product as your galaxy black keyboard is actual gun metal gray and your galaxy black mouse is straight black!!!

Dear Brian, Thank you for taking the time to share your feedback with us. We sincerely apologize for the inconvenience and frustration you’ve experienced with your recent order. The material and finish on the keyboard of Galaxy black is different from the X Pro mouse, which makes the color look different. If you are not satisfied with the color, we can offer you alternative ways to solve this issue. I heard from our service team, that they are working on the solution and communicating with you. We value your feedback and are committed to improving our customer service response times and overall experience. If there’s anything else we can assist you with, please don’t hesitate to reach out to us directly at [customer service email/phone]. Best regards, GravaStar Team
