Did not meet any of the criteria promised by the manufacturer
After extensive shopping and comparing I decided to purchase this mouse that I could not afford because of all the promises made by the manufacturer. They promised that it would work at any angle, and on almost all surfaces, even glass, at an unobstructed distance of 10 meters. It failed in every category. At an unobstructed distance of 7 meters it would not track accurately on any surface including the 3M Precise mouse pad. The design was very comfortable except for the smooth shiny plastic that stuck to my hand even when not perspiring, and did not have lotion, or any other solution on my hand. Cleaning with a clean soft cloth didn't help. I paid the lowest price of $41. I suggest shoppers check out the Perixx left hand mouse. It is identical in design, has a comfortable non-stick coating, and has a lowest price of $25, $16 less than the Adesso. BTW, my Delux brand mouse works perfectly at 8 meters, and my Logitech mouse works perfectly at a full 10 meters. All 3 mini receivers were connected to the same hub.
