It was delivered quickly, looks great and worked.
Now, after 5 months, he has been repeatedly described "double issue". Although he clicks only once, the mouse regaiert it with a double, making normal work and gamble with the mouse is no longer possible and he had to join his old, unlit mouse again.
Now I'll try to return and to get a replacement for the mouse.
Very annoying and definitely not a recommendation to buy !!
