Fast delivery, better than the stated time well packaged, correct for this type of object - in bubble envelope Product conforms to the description - the "mini" in the title should match the dongle, since the mouse is a standard size, but actually very thin, so "ultra-slim" a false fear: the small receiver dongle was not in the pocket ... ... But looking good, it was wisely tidy, safe in the battery compartment !!! not fault it, good functioning and very responsive I recommend this product and also its seller
