Well, obviously, the price is reasonable but it is good to know that the USB receiver spring roughly 2 cm. So it is mandatory to remove if you want to carry (in a bag) the computer. It has already been folded ... I also have a Logitech (but more expensive) and receiver out of 1/2 cm. The mouse is quite impressive (I do not understand some comments about his small size ...). The wheel / mouse wheel turns freely. Personally, I prefer that it is 'toothed'. Finally, for the price, not bad
