Genius Twin Wheel F1, Mini Vibration, PC/PS2 Combo Wheel

If you play any NASCAR game you know, you NEED a steering wheel to enjoy it correctly.
So I thought I found a cheap solution in the Genius Twin Wheel F1, Mini Vibration, PC/PS2 combo wheel.
Unhappily, mine came defective; The triangle button would stick when pressed and it took a flick of the thumbnail to right it. And as I have a mental disorder that makes me unable to send things I get in the mail back, I just dealt with it.

GOOD:
General. The unit worked well when functioning correctly.
Adjustable sensitivity. The unit has 4 sensitivity settings which are important when playing those games (NASCAR) where steering is challenging and the tracks have differing steering demands.

BAD:
No Documentation. It did not come with any documentation on how to program the levers nor could I find any online (surprisingly), so I was never able to do that, which is a shame because it has 2 perfectly placed levers, left and right, to be employed as shifters. Instead I had to use the R1 and L1, which are on the top front of the wheel and took my mind of racing for a second as I had to change hand positions to move my thumb to shift.
Shaky Quality. I play NASCAR about 3-4 times a week for around an hour per sitting. I’ve had the unit for 2 months and now when I turn to the left or move the wire in the back, the circle button function is engaged. So now it is a useless hulk until I open ‘er up and fix the connections.

In summary, IF the unit arrived functioning properly and IF it had documentation on how to program the buttons and IF it didn’t break after only 2 months, I would give this product 5 out of 5 stars.
