Very good mouse - scroll reasonable

It was so smooth that you just had to touch it and it has been scrolled.
Links I click many times with the middle Maustatse in to open it in a new window - it was almost impossible with the M325.

Now for M235
+ Scroll smoothly but with noticeable dithering (ideal!)
+ Small and handy
+ Very good recognition on a black background (my old Logitech RX250 hate so problems)
+ Receiver unit stowable
+ Receiver on the PC behind aperture used
+ Very long battery life (have the previous model Logitech M215 for several years, battery holds loosely over 1 year, of course, vary with use)
+ Only 1 AA battery required

I would buy again the mouse!

Update after more than 1 year (03.01.2014): mouse still works perfectly, it's still the first battery in it and the PC is used daily. The mouse I turn not from. So be it - still buy recommendation!
