The worst keyboard I have ever used in my life, for the past 3 decades. Very cheap plastic, it bends in the middle from the beginning and you can't press the keys without force and effort. A cheaper Xtrike Me keyboard that I bought for the office is much better, as well as a Dell one that immediately replaced this Conceptum at home. Stay away, unfortunately it's a waste of money.

By far the worst keyboard I have ever touched.
If you press hard on a key in the center and have the legs open, the entire keyboard bends.
If you fold the legs, it slips because they haven't put any rubber cover on the contact points with the desk.
The keys sometimes don't register at all and other times you press and they register three times.
Sometimes they get stuck and stay pressed down without registering.
The mouse seems to be working fine for now.
It's definitely not worth it as a main keyboard, but as a backup if your regular one breaks on a Saturday afternoon.

If you buy it, you will put it in the closet, as a backup, in case the other one breaks and you are forced to buy a new one, after you realize that this one is garbage!!!! Absolutely useless!! The keys stop working after a while unless you press them hard, and you can only write slowly and with obstacles. Forget it...!! The best DISGRACE for this company...
