Great deal key board is a little fragile feeling but it works great and the keys are very soft feeling when pressed the mouse is solid though for sure.

smooth, good size and quality

Feels good in the hand (I have medium sized hands) and is perfectly functional. i really like the sensitivity profiles that you can change with a small button right on the top. The battery life is very long as well. Perfect weight!


Great build quality, Solid touch feeling

1. Large surface area and ergonomic design makes it fantastic for larger palms and stubbier fingers. 2. Has 12 customizable buttons that are useful for basically any titles with lots of hotkeys. 3. High acceleration and polling rate. 4. Fast and light scroll wheel.

Comme dans le bon vieux temps ! Ajout de la souris sur Bluetooth et elle fonctionne comme un charme depuis ce temps (1 mois). Bon achat.

Fast and reponsive.

It works well.

This keyboard has an accurate trackpad that doesn't jump all over the place, there is no lag between keystrokes and my cats tail doesn't interrupt the signal between keyboard and computer. Compared to all the other wireless keyboards I have tried the K400 is a joy to use.


Was looking for a gaming keyboard to make playing PC games on a gaming laptop better. Found this and love it -- makes playing games easier and more enjoyable. Plenty of button options. Really like the various RGB settings Doesn't take up that much space

Works great, feels good in hand

Nice feel. I got it on sale, wish I would have bought 10 of them!
