Long decided whether to take or not. I do not regret the purchase! For the keyboard is just fire! It does not creak and does not bend - it is clear that the device is not all plastic. And the buttons are pressed very nicely (the sound is not loud, not annoying). How long the battery lasts - I can not say yet. But for two weeks I have been using it with backlight - so far everything is fine. The backlight is great too. Brightness adjustable or off altogether. At night, everything is wonderfully visible, while not blinding or distracting. - I won’t even write this in cons, but it’s worth saying: - the reaction of switching on the backlight with a slight braking. That is, it does not turn on immediately, but after several touches. - there is no height adjustment (at the same time, there is already a certain rise). - TOTAL: Expensive but very cool! I don't regret it. Very, very worthy device. Please yourself - that's it!
