Reliable product
I would buy again. Quality construction. I searched every where looking for right size for my 2006 Volvo. No auto parts store in town carried the right size. Only big cities in Arizona have Volvo dealers. The closest was Vegas and Lake Havasu City. Thanks to Amazon saved me a long drive.
