Excellent for a reasonable price

By dint of using the computer, I have tendinitis in left wrist. This keyboard allows me not to feel pain and changes life!

For the convenience of the keypad, some keys are a little gadget but, overall, it is very convenient.
It takes a little time to adjust the positioning of the buttons (see 2 1h as usual), but once that is done, it is very comfortable.

Whether it's on a MAC or Windows, it has many useful shortcuts and filled his role perfectly.
Sound management include (mute, volume, play / pause), the possibility to use the function keys (F1, F2 ...) Classic or shortcuts for office instead (Cancel, restore, new, open ...) for these functions, the change from one mode to another is done by a simple touch. Anyway, a lot of available shortcuts without it becoming complicated.

The only downside that we can find him is that, as shown in some reviews, the buttons disappear over time (as seen on a keyboard having 2 or 3 years). Fortunately, this does not affect its working.

In the end, I recommend it without hesitation, this is an excellent price / quality ratio.
