Positive is the small size, but this comes at the expense of ergonomics. But hey, I personally see notebook mice anyway rather than emergency peripherals on the go, for less intensive work, so I want to give on the basis of which no depreciation.
However, what bothers is the fact that the grease runs down the scroll out of the opening in the vertical, forward facing position, after a while. This lubricant is extremely bad from the surface to remove (even with alcohol-impregnated wipes only with a lot of patience) and annoying while working. Too bad, otherwise the M325 Logitech would be a true five-star product.
The exchangeable battery life is indicated by average 18 months. If you are not a power user is (power users use different mice), this information comes out easy. I had even not believed.
If you know the deplorable state of the grease and one in the storage bit makes sure I can warmly recommend the mouse. I would buy me back.
