I had a locked up seat belt & SafetyRestore repaired it for me, seems to be ok. My biggest complaint overall is how long it took to get the belt back. It was repaired and shipped out the day after it was received via Fed Ex ground. It took 10 days to get delivered. I had sent the belt to SafetyrRtore via Express Mail that cost $12 and was delivered in 2 days. SafetyRestore charges $15 for the shipping why they could not use express mail is a mystery to me. The other thing is that I wanted to know what caused the problem since the vehicle had not been in an accident. I called and was told belt assembly had been completely rebuilt. However, I could see very clearly that the original gas charge had not been replaced ( I took a picture of the worn and scuffed up OEM label) though Safety Restore told me that it had been. I have a warranty but have to wonder if it will be honored if I have another problem with the belt.
