Coolest keyboard ever. Looks great, sounds great, feels great. I wasn’t expecting the keyboard to be as solid as it is but good heavens, she’s solid and durable. I don’t think i’ll ever buy a different brand again - Gravastar for the win

I bought the Mercury M1 Pro (Gunmetal Gray) less than two years ago, and it’s already reaching the end of its life. A full charge lasts about 15 minutes, so at this point it’s not even a wireless mouse anymore. I do love the design, but it’s a pain to clean. Honestly, I wouldn’t recommend any of their products. It basically turned out exactly how I expected when I bought it — sure, it looks great, but underneath it’s just an overpriced Temu-quality mouse.

Hi there — thank you for taking the time to share this feedback, and I’m genuinely sorry to hear about your experience with the Mercury M1 Pro. A full charge lasting only ~15 minutes is definitely not normal, especially within two years, and we’d like to make this right. Please contact us with your order number and the email used at checkout so we can check warranty eligibility and arrange a solution (replacement/repair options depending on the case). You can reach us at [email protected]. If you prefer, you can also reply to our “Request information” message here on Trustpilot with your order details (no need to post private info publicly). We appreciate you loving the design, and we’re sorry the performance didn’t meet expectations — we’ll do our best to resolve this for you.

So i have only ever bought cheap keyboards my entire life and I seen someone (can't remember who honestly) showing off a wild looking keyboard on facebook. So I started looking on your website. At first it was a "NO" from the price alone, but I kept seeing ads for your products. I work full time and decided to splurge a little on myself so I went with not the cheapest, but also not the most expensive keyboard I could find. Site navigation was a dream, everything nice and neat. I decided on the K1 mercury gradient black. I ordered late on a Thursday night and the product was to my home, on my porch the following Sunday morning. Perfect. I did a small unboxing video so my friends and family could halfway enjoy the experience of opening up one of your products. Everything was beautifully packaged, nice and neat. Everything fitting snug in the box. The keyboard felt great in my hands and looked even better in person! I placed on my desk and I was already in love with the first couple key strokes. You can really feel the quality of your product. I put the unboxing video on 3 social media accounts of mine and the cpl videos I made has already received thousands of views combined. Id give you guys 10 stars if I could, you deserve more than the standard 5, I can tell you that. I write reviews on products as well make small videos to share with the world so thank you. Ill definitely be ordering another one when I wanna change up the style, im already seeing another one id like to have, as well as a Bluetooth speaker. Thank you so much Gravastar!
