Good value. Worked well with no issues. Extra long cable is a plus!
I had my doubtts because of the cost but this is a great replacement part, Installed with no issues and connected fine to a 2012 Chevy Cruze. The extra long cable is a plus.

I thought buying through Amazon would the best option for a simple part which is was cheaper but the actual part only lasted a couple months and had to replace it again. I decided to find the part through an aftermarket website and though it wasn't cheaper but I found that it is best to go for quality than cheapness.
