Defrost
Defrost works flawlessly.

20+ silverado heated lower mirror glass
Lower mirror glass fits and operates like OEM. This is something GM should do on an 80k dollar plus truck. Thanks boost auto for providing us with a solution for GMs shortcomings.

Easy and a great upgrade
Very easy to install and makes plowing so much easier

2019+ GM heated lower glass.
The glass was delivered a head of schedule which was nice. Install was a breeze, and they work like a charm.

Seems to work as of now
The install was pretty straight forward with no problems. I did notice the pattern in the glass is not the same as the factory. While the glass still does its job the lines are different
