Summary: I purchased this Saitek P2500 game pad to replace a Microsoft game pad (the X-axis toggle broke off due to cheap construction).
I've been very happy with the Saitek, particularly the ergonomics and the quality of construction.
Ergonomically, the game pad fits very naturally in my hands and the buttons are well laid and intuitive. I don't have to hunt and peck for my controls when I play a game.
Summary: This is a great controller. Built in rumblepad, sexy blue light and it works great. The 2 and a half stars are misleading to those who are looking for a new game pad for your pc. Get this, at $22 it's a solid deal. Only downside is you might want to buy a usb extension cord because I believe the stock cord is only 2 feet long so if you are planning to sit on the couch further away I'd recommend getting that USB extention ;)
