I have 2 keyboards, Logitech's wide k280e at home (it costs about the same as this one). And for work in the office for a laptop, I bought this one, small software. And in vain. Logitekovskaya is an order of magnitude more convenient and pleasant to respond to the keys, it’s just a pleasure to work! And you never smear with letters when touch typing! With its pros: Norm Claudia, seems to be reliable (at least before, microsoft mice served me for a long time). Different cons: The keys are too close to each other, not for a large and even average male hand. It quickly becomes covered with dust and this is very noticeable due to its partial glossiness (again, I compare it with Logitech's).
