Well, I am on my second G25. I had the reverse gear go on me. It showed sixth gear in sixth and reverse. After a bit of a run around, I finally got an RMA from Logitech. They totally agreed that the shifter was broken. Unfortunately, they wanted the whole wheel, pedals and shifter back for replacement.... at MY cost for shipping. I live in Western Canada, and Logitech is in California. 30 some Canuck bucks later, I agreed to ship.(Overnight shipping was more than the cost of the wheel). They eventually sent me a brand new wheel, all very nice, but the reverse gear died with a month.
I'm not sending it back...if I want an h-shifter, it's gonna be a 5 gear transmission. All that negativity aside, it is the best wheel I've had.... bar none! That list includes the thrustmast t1 (elastic band centering), the red Momo, and the black Momo, which is my backup still.
