A revolution and many setbacks

I have the MX Revolution now one and a half years, it is basically a very good mouse with scroll wheel as their "revolutionary" unique selling point, however, from the perfect mouse is still a long way away, primarily because of their limited shelf life:

Design / Ergonomics: The MX Revolution looks good, the materials used are of high quality and show outwardly after eighteen months of regular use no signs of wear. A minor annoyance is the color, as the MX Revolution Logitech product is not naturally pure black (that would be too easy) but the top is painted in a dubious dark gray, which is probably used for anything in the world otherwise. So how many Logitech products dances the MX Revolution on the desk visually from the series. But that's a matter of taste. The MX Revolution is pretty good in the hand, though not as good as the MX 1000 as it is much smaller and narrower (but such assessment is probably out of hand size from, but I have pretty big hands).

Functionality: There is nothing to complain about, the innovative mouse wheel alone is a reason to buy the MX Revolution (or was it at the time when I bought it, now there are already other Logitech mice with the same wheel), as it working with long texts or tables much easier. Of course, it is very precise and slides perfectly. The extra little buttons and the wheel side are a nice - and sometimes useful - gimmick, but in itself is definitely not a reason to buy the mouse.
The (necessary) driver software works well and offers many setting possibilities. Problems with connection problems I have no more, since the receiver is on the desk with. Visual contact between the receiver and mouse is recommended in any case, otherwise the mouse hooked sometimes noticeably. The specified range of Logitech is thus to refer to the realm of legends. A real progress compared to the MX 1000 is the charger that charges the mouse without complaint and immediately (and without much fiddling until the mouse is loaded as the MX 1000). The store could go a bit faster, but is acceptable.

Battery: The MX Revolution battery is built and can not be changed (at this point under "Shelf life" later). He is not particularly efficient, especially significantly weaker than that of the MX 1000. For intensive use mouse selbige (two to three days) has after a short time to the charging station to give the MX 1000 it was less than a week. When I marveled demand towards me has been confirmed by Logitech as the normal. After all, the MX Revolution has a quite fine charge indicator.

Durability: This point is the great weakness of the MX Revolution. It is, you have to say unfortunately so designed as a disposable product, which does not fit to the premium quality, the Logitech likes to see for themselves. The batteries are not only not reversible, but it is also a clear deterioration of battery performance after one and a half years noticeably, so you probably can throw away after three years a good piece with frequent use. Also the mouse wheel does not seem to be designed for eternity, my turns to one and a half years in any case, only very difficult, which is why the mouse was exchanged. A total of three defects have occurred to me in one and a half years. First (two months after the purchase), the mouse was replaced due to insufficient battery life, after one and a half years due to a broken scroll wheel and after the then delivered (new!) Replacement unit from the outset noticeable made by a high-frequency fiependes PSU, now a third and last time.

It remains an ambiguous conclusion: First, the MX Revolution is an outstanding mouse whose mouse wheel you will not want to miss a very short time, on the other hand it is a disposable product with a manageable life expectancy simply too expensive. Unfortunately, the recently launched MX 1100 is clearer for ergonomic weaknesses no alternative, although it is doing in terms of the durability of some much better than the MX Revolution. Without the durability problem the MX Revolution would be between four and five stars (for ease of design and ergonomics weaknesses), with it they can not get beyond three.
