I've had mine on since November.. Delivery was quick enough at the time
As people say, you get what you pay for. The ride is shockingly hard, the car is also bouncy which isn't a good combo. They're fitted easy enough, nothing out of the ordinary. Mine have lasted and aren't really showing any signs of failing at all, I can see what Mikester says about the rings being made of cheese, but saying that I haven't had any problems so far
Altogether if you want to lower your car, but don't care for ride quality, buy these.
