Paddle Shifter is a great product and easier to install then the videos made it seem and fast shipping. I will definitely be ordering other products soon.

Fantastic product! I’m using this with the hand brake mini and some goon tape for the vibes! I had to leave some space between the handbrake and the rail panel for my large hands, but it is a very comfortable setup ! Love the grip it provides, as well as a barricade stop on the front of the rail panel!
