Ordered, delivered and already they were there. Of course, equal unpacked and my first impression was neither surprising nor negative surprisingly positive. The other two, one was also from uping and the second of Perixx, were also very comfortable to hold lying ... sometimes even better in my opinion, because they were built ergonomic. They also had a back and forth button which is very handy for surfing and working on the desktop, but when I had this mouse in use, I was totally impressed by the clicking noise!
Although it has no backward and forward buttons and perhaps is not quite as ergonomically in the hand, so I had really considered long, but in my case, this ultra soft click some benefits! Especially if you have sleep and work in the same room and maybe the girlfriend / boyfriend would not like to wake up, clicking but by constantly!
The sensor may not light up, which has at the beginning a little irritated me, but it works on various substrates excellent! You might be a little harder and maybe a little gummed on pages, but as I said, at this price I am deeply impressed by the clicking sounds!
Long-term test, there is unfortunately no, because I have only been 3 weeks, but so far everything is fine;)
