It auto clicks and auto closes windows constantly even with hover select turned off to the point of being unusable with the track pad. It is useable with a mouse, but still supper aggravating. The auto click and constant window closing keeps happening, but you might get 3 - 5 min. in before it closes the window you are working in rather than every 2 seconds with the mouse. The power cord us unusable. At 44 inches long it can reach straight down from a desk with no lateral movement. It's a nonstandard cord, so buying a replacement isn't possible without more information than the seller has provided.
