It works very well

It’s a necessary part, especially if you don’t have a handlebar that allows the end junction box. It is easy to install, and works well to charge the system and program/adjust the shifting. I did not like the adjustable strap to mount it, and instead purchased the K-Edge mount to install it directly…
