Here are my impressions:
Range: 4-6 meters therefore are not a problem. Depending on how directly the connection.
Precision: In almost all substrates I have good experiences. Desk, trouser, plastic back of the chair, metal table, ... For surfing and Ofiice and so on goes the mouse completely. To play it is only conditionally suitable I think.
Noise: In itself, but the mouse is fairly quiet in the UNI / library it is clearly too loud. Since I have made a small improvement and it made "silent". It's very simple leaky can explain how to do it on request!
Now the mouse is perfect for my needs! Precise, quiet, light, robust - that's all you brought.
Whether the battery now holds by 11 or 12 months I do not know but I can observe the times ...
PS: The price is fully in order (and discounts for 15 EUR) and Those who try something fumbling and is technically not completely untalented, which can be screwed the part once and also make noise!
