Delivered fast and in great fashion! Packaged clean and securely and the keyboard is everything I hoped it would be. A very creamy mechanical sound that isn’t too loud or obnoxious, and the mouse is light but comfortable with a expensive feel to it. The keyboard feels like it’s about 5-10 pounds and I love the fact that it’s heavy. Easy to setup software for rgb lights and customization! Definitely buying my next keyboard from these guys!

Order #GR129010 / Affirm loan JYE5-LLRG / $222.26 — Mercury K98 Pro. Never shipped. They confirmed cancel + "full refund processed" in writing, then flipped to: withdraw the Affirm dispute first, or wait Affirm's clock. On Sep 18 they emailed their own Shopify screen showing Paid / Unfulfilled / Chargeback open $222.26 with evidence controls still available (deadline Sep 25). So they can accept — they choose not to. Then they asked me to delete my Trustpilot review. Don't buy from GravaStar if you need the order to actually arrive or the refund to stick.

The Mercury X Air 8KHz Wireless Gaming Mouse is one of the best mice I've used. It's lightweight, accurate, comfortable, and incredibly responsive. The wireless performance is flawless, and the battery lasts longer than expected. The V60 Ultra is equally impressive with its premium feel, unique design, and excellent overall performance. Both products showcase GravaStar's commitment to quality and innovation. If you want gaming gear that stands out from the crowd while delivering top-tier performance, these are fantastic choices.
