I initially tried to return my order because the product pictures on the website were (atleast to me) misleading. Ordered a Qwertz layout eventhough the pictures showed Qwerty. Unfortunately, I received no response from customer support despite emailing both the .DE and .COM addresses. They reached out to me after a few weeks in order to sort things out. That said, the issue was eventually resolved. I received most of my money back, although I had to pay for the return shipping myself, which is understandable, and the original shipping costs were not refunded. The process took quite a while, but thanks to Suki from customer support, everything was sorted out in the end.

Dear Roberto, I am truly sorry for the lack of response you experienced and the frustration this has caused regarding your return. This is certainly not the level of service we aim to provide at GravaStar. We want to look into this immediately and make things right for you. Could you please contact us directly at [email protected] with your order details? We will prioritize your case to ensure your refund or return is processed, regardless of the 30-day window passing due to our delay. Thank you for bringing this to our attention, and we appreciate your patience.

Me and my girlfiend received two different pairs of GravaStar headphones as gifts (Sirius PRO P9). While the design is incredibly unique, the hardware quality is unacceptable. On both units, the batteries completely failed after minimal use, and now hold a charge for less than 5 minutes tops. When I contacted customer service, they confirmed the units are completely sealed and cannot be repaired. However, because these were gifts and I don't have the original order number, GravaStar refused to honor a warranty replacement—even though I provided the physical serial numbers proving they are authentic products. If you buy these, know that you are buying a disposable product. If the battery dies, or if you receive it as a gift, customer service will just offer you a discount code to spend more money on another faulty unit. Buyer beware. UPDATE! after the company’s public reply: I contacted GravaStar again exactly as requested and referenced this Trustpilot review. Unfortunately, despite the public statement about “reviewing the case” and “finding a better way forward,” the final outcome remained unchanged. The headphones still cannot be repaired because the units are sealed and no replacement batteries exist. Although I provided authentic serial-numbered products, GravaStar again refused warranty replacement because the headphones were gifts and I do not have the original order number. So to clarify for future buyers: the public response did not result in any actual resolution, exception, or replacement offer beyond another discount code to purchase a new unit. The design is great. The battery reliability and warranty support were not.

Thank you for sharing your feedback, and I sincerely apologize for the frustrating experience you and your girlfriend had with the Sirius PRO P9 headphones and our support team. We stand behind the quality of our products, and experiencing a battery failure on both units is definitely not acceptable. While our standard policy requires an order number to verify warranty eligibility, we understand that this is a unique situation since they were received as gifts. I want to personally review your case to see how we can assist you further with a proper solution. Please reach out to us at [email protected] and mention this review so we can find a better way forward for you.

Amazing, the keyboard and mouse are good quality the keyboard is heavy and the mouse is less than 50grams Originally I thought it was plastic but I looked up that magnesium alloy is very light, and that made it even better! Keyboard : well made, Great online software and user friendly set up within 5minutes. Mouse: well made, Great online software again, super smooth to glide around dpi settings and poling rates amazing. Price : was in USD expensive but well worth it! Future purchase : Yes! Customer service : I felt when contacting the customer service it was AI I was talking to and I didn't like that Delivery : from China to Australia it was well backed box was damaged but product was fine Suggestions : start making computer cases that match the keyboard design as I would love my setup to match it all. Conclusion: if you want a good keyboard or mouse I would strongly suggest gravastar as my other keyboard I have had since 2015 and I have not found a keyboard to replace it until now I feel this is it and that's 11 years of searching for a keyboard, the mouse I always have a mouse that is plastic and rubber and my hand sweat eats away at the rubber ruining my mouse, so this.mouse being metal skeleton allows my hand to breath while gaming and even though the magnesium alloy corrods over time gravastar has added a protective coating over their mice. I hope my review has helped you decide on whether to buy or not.

The Mercury K1 Cloud keyboard was exactly what I was looking for! 75%, Gradient from grey to white, shine through caps, plug and play integration with SignalRGB, unique metal frame, great keystroke feel, the customizable RGB side lighting was a huge plus (fn + shift and fn + ?), great price point. Super happy with this thank you!

Initially, I had a very frustrating experience because my package was marked as delivered but never arrived, and communication from support was very slow. There was a lot of back-and-forth emailing and waiting throughout the process. However, to be fair, the GravaStar customer service team eventually contacted me and arranged a replacement shipment. I have now successfully received the replacement package, and everything arrived safely and in good condition. I still believe the communication and support process during lost-package situations could be improved, but I appreciate that the company ultimately took responsibility and resolved the issue.

I am sincerely sorry for the frustrating experience you’ve had. As a member of the GravaStar team, it pains me to hear that you’ve been met with silence after not receiving your order. This is absolutely not the level of service we strive to provide, especially for our community members. Regarding the issues with the carrier (Better Trucks) and the lack of response from our support channels, we take full responsibility. We are currently reviewing our communication internal flow to ensure no customer is left in the dark like this again. I want to make this right immediately. Please contact me directly at [email protected] with the subject line "Urgent: Attn Shopify Manager - Missing Package" and include your order number. I will personally oversee the investigation with the carrier and ensure a replacement or a full refund is processed for you within 24 hours of your email. We value your support and are committed to regaining your trust.

The keyboard feels like an old hotwheels, the same kind of metal, heavy but by that reason feels of better quality. and already configure the keyboard to react with the led lights. I love the keyboard.
