Feel, weight, size and shape all play a major role in the design of the remote. The battery life is exceptional and it has different modes like for playstation.
Works well, my nephews have yet to be able to destroy it (5 and 7 years old). Have ordered another.
I use this controller for emulators and a few games on Steam. It feels great and I like the responsiveness of the buttons. There have been some complaints about the triggers, but not from me. Logitech's website provides the drivers/software for it, which are adequate. If you want a good, sturdy PC controller, this one is perfect.
Great wireless performance. Comfortable leather grip. The buttons are responsive and have a nice spring feel to it (especially L2 and R2).
