Very good. It offers very good protection in case of vehicle contact with the wall - corner). Very easy to install (I installed 2 in 15 minutes). The material is quite thick...visible (especially at night as it should be) and gives you an accurate image (e.g. when reversing) of where your vehicle is exactly with its reflectors. I definitely recommend it (especially if you wear glasses or have difficulty parking in tight spaces)...it will help a lot, just like it helped me!
