Love the keyboard and mouse! Would be pretty cool if there was an app control for the customization.

The products are verry high quality
By Olivier K.
Very good keyboard (v75 black) with a faster delivery than normal. and with a concern on my part they responded very quickly. I recommend

I've got to say the quality of this product is above and beyond excellent. The attention to detail is exquisite; as is the performance. You just can't beat the clickity clack of the switches as you speed along. The RGB is set up to act like a drop of water hits the keyboard each time I press a key. I feel like I'm in a futuristic wonderland every time I type something. I use it for Solidworks design which makes it overkill for that application, but I still appreciate every bit of the Gravastar Mercury K1 as I design away.

It was my first time ordering from the website, previous products gain my interest for how well made they were and attractive, and with the new keyboards and mice it felt like a more premium experience. My words can’t describe the satisfaction and simplicity of ordering, everything is so clear from shipping info and easiness on payment.

I love the Gravastar Mars Pro! What an amazing speaker. Not only does it look super cool, but the sound is so much better than I expected even. 100% worth the buy
