Too Tight but It Works
It doesn't really sit on very well to be honest, it tends to sit TOO tight in my opinion. Taking it off can be a hassle but at least it gets the job done, durability is good, finish is great, obviously easy to use.

Perfect fit
This product was a perfect fit on our 2009 BMW 328i. It was alittle difficult connecting the hose at the bottom because my husband has big hands but I was able to help tighten the screw Due to my smaller hand size Overall very good product and fast delivery
