I have a very similar older Saitek gamepad (no rumble) and my only complaint is that for some reason the axes on the left analog stick are backwards (left<->right is up<->down, vice versa). No response from the one time I emailed them about it, but it was only ever an issue in games that didn't have an option to remap controls. No idea if this is even a widespread issue, IIRC I bought it 3-4 years ago.
Definitely worth $8, IMO.
Oh, also, there are six face buttons and two shoulder buttons.
