Addendum: The shipper has very promptly responded that he has earned one star. And only.
The delivery then took another 9 days. Two mice (without batteries) in padded envelope.
The mice in line with expectations: cheap! Feel so-so. But as can be expected at this price nothing else! So no criticism. What two of the additional buttons will cause, I have not yet figured out, they can not be configured on my Dell Latitude any case. At least bothers me not great because I do not need. Annoying are the Gleitpads that not just glide.
But what (ver) interferes: The first mouse has constantly led to the freezing of the laptops, at plugging of mouse No two the problem was no longer in the past.. I do not know what it is, for 6 but I have no desire rumzudoktern long. Starting in the trash so.
Sorry guys, better things will not go. The product is recommended and does not remain.
