Logitech is me actually known as a producer of useful hardware. Clear gibts there also crap, but not only - that can also what. I thought of this mouse is Logitech which once again demonstrated.
Well ... well. Not quite. Unfortunately.
The mouse is generally large class, really great - and I like everything about her - except for the processing. Which unfortunately only moderately successful. And for that, the device is then but a little too expensive. In ner mouse for over 50 you want a little bit what to expect. Something like "working key", perhaps.
Of course, the mouse worked when I've bought. In fact I use to about ten different PCs such mice of different ages. Private that is now my third. As already the predecessor model qualitatively lousy switches were also installed here again and after a while is from nem simple click just a double - or even none at all. This occurs when too many devices, as that one could call it "random". Logitech knows it, the problem is known.
The thumb button, the "hidden" is under the thumb rest, you can not take it seriously. Even if it is this key only extremely rare defect operated relatively quickly. So - completely defective. This is probably attributable to not only the processing but also a design flaw.
The side-mounted buttons (forward, back, zoom) function well. The mouse buttons (left, right) only until just the switches are defective - that is probably different depending on usage and device and I suspect my stress you may not see it as "average" here.
The mouse wheel is initially perhaps Ungwohnt, but it is good enough now.
Of course, this is all a matter of taste, but all - so genuine, all - materials Logitech has chosen for external, visible surfaces of the device, are anything but "valent". When the mouse was used first for a while she sees quickly "taken" from. The appearance of the device is only good for product photos or for shelf.
There is only one reason why I, despite their weaknesses still three stars give this mouse ... its competitors cut not really better, because I have done even worse experiences.
(I think essentially not bother me some shortcomings, mainly bothers me the observable decline in quality. I hope the company afford in the future again to bring a few more cents cost to also again reasonable mice with long-term benefits to the market .. .)
