Overall a good quality mouse. Of course, there are disadvantages, but any mouse has them. This one has probably less than any other. If you like mice with lots of ons, you won't find better. Here they write that the form is not that big, that the ons are unnecessary, etc. So, this is all complete ! If you know why you want this mouse - feel free to take it! And if you yourself don’t know why you need it, it’s better to look towards more clic models.
