did you have to install the software to use the mx master 3? i've been reading a lot of negative reviews about the software eating up a ton of resources, but without the software things like horizontal scrolling doesnt work etc.
its not personalized. Funny story. My wife tried it out one time, and we went to meet up with a friend who we haven't seen in 5 years who just came back from working in Japan. The friend and my wife have vastly different body types, hair colors, height and style. Guess who ended up matching exactly in clothing for the night?
