Quality seems good, but....

The throw is way too far for engagement. Getting used to it but will eventually swap it out for something else. Using it paired with a bikeyoke post replacing the original bikeyoke remote (which broke).

Andrew Yamada
Great to do business with Thunder Mountain.

The customer service was quick to respond an order change and ship the product next day.

Jeff Cocking
Great post

My v1 post was finally getting sponging after 6-yrs of no maintenance and thought I would go for more travel. Great post, great service by TMB!
