More than fair for the price
I bought this keyboard to replace my Cooler Master Devastator 3 mecha keyboard, which had outlived its usefulness (good value for money, it lasted 3 years).
The Xpert-K 900 :
Strengths:
- Opto-mechanical, the feel and responsiveness are really good for the price
- Aluminium front panel
- No rim around the keys, which makes cleaning very easy
- Practical sound wheel
- RBG settings via modes programmed into the keyboard are very easy to learn (everything is in the manual)
- Solid braided cable
- Key extractor supplied
Weak points :
- Quite noisy, but you get used to it
- The wrist rest is not comfortable enough and the tilt means that the wrist is slightly broken. Paradoxically, it's comfortable for typing, but for prolonged gaming sessions it's a few mm too thin in my opinion.
- The 'Enter' key didn't work properly when I first used it. I had to remove it and replace it. Now everything works properly
