Excellent, as always with Logitech.

I bought this keyboard following the death of my old E Logitech wired keyboard key.
Given its price, I thought that a chicklet keyboard and wireless would be nice to use everyday.
I'm not wrong!
The first 10 minutes are laborious, difficult to adapt to the spacing of the keys when you're used to find his fingers!
But after this time, a treat!
It is ultra quiet, pretty amazing actually.
The keyboard is tiny, I understand why it is destined to a laptop. Yet even with my hands lumberjack I have no problem finding my bearings.
The format "flat" mode is very interesting, it gives a small side "Macbook" on my pc :)
Many thanks to the customizable shortcuts Logitech software (which I already was using for my mouse to install anything more!)
And to finish the "black striped" coloring is more enjoyable!

The qques negative points / to check on the duration:
The placement of some keys may be difficult to remember, especially if like me you use a keyboard "classical" work ...
I expect a lot of battery life promised by the manufacturer! I doubt go until end of 3 years, but if it already exceeds the year and a half, I'll be satisfied.
And remains to be seen if the finish will be as good in a few months / years, whether the keys are commener to fade and / or become "smooth", if you see what I mean.

Anyway, a great cheap little keyboard.

EDIT: After 2 years of use (23 months to be exact), I still have not changed the batteries, Logitech thus not lying about the enormous autonomy!
The keyboard is always nickel, no trace of wear, no erased key.
The "weird" positions which I spoke in 2011 at the final NEVER asked me worries.

Anyway (twice), I am very satisfied with my purchase ... of it two years ago :)
