If you're a tall guy and want to push the bucket seats way back, these might not work for you. Overall, I like them. The quality of the belt material is very good and I like the buckle design. I don't feel like the retractor is very strong and the extension at the bottom tends to pivot if you don't tighten the bolt very tight which can cause the belt to droop (not retract all the way).
