They are expensive, but if mine broke I’d replace it imediatly.

I snapped the trigger on my RS Reverb remote with my shorts (my fault) and went riding on the same day with my old Easton Haven post
hated the lack of fluidity in my riding as my left thumb kept going for the missing remote trigger..and was riding some very hilly terrain with steep descents where I had to stop and lower the saddle manually, and then raise again for climbing
once you get used to them, its really hard to go back, and it has a definite, positive effect on your riding experience
thankfully got my Reverb back within a few days replaced FOC under warranty and thoroughly enjoyed my next ride!
