It doesnt seem as responsive as my right hand logitech thumb roller but it does the job i had to search through amazon to find it though

My only critique would be that button responses are incredibly light forcing me to rest fingers in nonswitch positions when not actively clicking

After all this is the only left handed track ball mouse i can find

The only thing i dont like about this unit is the angle of your wrist when holding it

One other minor complaint is that the rightmost button seems to get in the way of the middle button they rub together at the front of the trackball

I dont even have the rightmost button assigned to do anything but i sometimes push it by accident when hammering the middle button

I have been using it for about two months now everday on the h setting which drains the battery faster but the supplied battery hasnt given out yet

I tried the kensington orbit wireless mobile trackball but gave up after a few weeks because the scrolling ring made the pointer jump all over the place
