Actually, the mouse comes to technology, service, look and feel is really good. Unfortunately, they are, as already described several "stakeholders", to approximately 1.5-2 years the ghost. The problems have been described here: First, it takes a few seconds, am it is usable in Windows, then falls either the Y- or X-Sensor from. Two days later, then goes as good as nothing.
As if a chip that thing after 2 years demolished on purpose anyway ... Have me again an ordered, since, as already mentioned, its purpose fully met and the product is really good. However, longevity is a disaster. I buy for this price not sure every 2 years a new one.
