- Soft, pleasant keys (I type quickly with a blind method, this is important for me). Well, the icons, of course, are covered with protection - the letters will not be erased in any way. Do not fill the keyboard with tea and coffee - a special design prevents damage to the keyboard: the liquid will simply go to the table through the holes (the photo shows the design of the buttons). It just needs to be taken apart and washed. Easy to understand! I took it apart and washed it twice (I don't like a dirty keyboard), no problem. The buttons are easy to snap off (except for the space, it is large): pry the top edge with your finger and that's it. Inside there is a membrane construction, elastic band is soft: after 4 years they look like new. Batteries last for a very long time - change every few years. There are no LEDs, but I think that this is an advantage.
- The receiver does not seem to be very good, at a distance of three meters from the computer, in which the receiver was turned on at the back, the keyboard did not work well, I had to bring it forward on a USB extension cable. Short left shift.
