Absolutely. Synergy is a great product for multiboxing. I wouldnt box without it. I mainly use it to mouse seamlessly from one computer to another in a multiple computer setup for looting, accepting quests & other general mouse based tasks.

It does have one minor annoying bug, if I try to click too long in 1 area on a secondary computer, that char will spin like a top, until the mouse button is released. There are supposedly work-arounds for this, but I havent gotten anything to work.

Bottom line, it isn't perfect, but it works, & you certainly can't beat the price: FREE!
