Very good! 1 5503

This wireless USB mouse is great, the coating is nice, I find it a bit lighter (about 70g without batteries) but I was used to a big thing from Logitech. Despite this, it sits well in my large hand, an on / off button to turn it off and a slot is provided on the back for the nano receiver.
DPI change accelerates the cursor, it is ideal for standard use.
And more and more the two 1.5V AAA batteries are included!
Amazon express delivery and good packaging, as usual.
So what else?

EDIT: actually, as has already been pointed out, this mouse crashes repeatedly for several seconds randomly and for no apparent reason.
Despite the apparent qualities, this problem makes the product unusable.
