Summary: Great in the hand, not too expensive, rumble motor works well, and easily works with most steam games, unlike some other cheaper units which do not do actual xbox 360 emulation without extensive software setup
Summary: So the controller itself works fine, but coming from someone who has played with the playstation 1 through 3 controllers many of days, the controller doesn't feel good. The GOOD is the price, vibration, and the bottom triggers. The not so great is: the feel, the analog sticks, the buttons, the D pad; pretty much everything else that isn't good is not great.
Summary: After repeated Steam sales, I found myself with some games for PC that were clearly console ports, and for those, rather than slogging through bad keyboard mouse controls, I broke down and replaced an aging controller. This pad has been a great performer for 100+ hours of Dark Souls, a run of Fable 3, and a few other hack and slash adventures. I can easily recommend this, if you're looking for an alternative to just using an xbox controller (or just don't own one).
