This shifter literally fell apart after several months' use. To VO's credit, they replaced it immediately, no questions asked. Still, I cannot recommend it due its self-destructive tendency. Oh, and the matching rear derailleur just last week had one of the jockey wheels fall out while I was riding.

This shifter works pretty well. I actually like it more than the road caliper shifting (I have both). I feel that when I had the road shifter, I would skip and stuff. the down shift on this one however is a lil rough but that doesn’t bother me, it’s prolly breaking in or something. So far so good, I use it with the 11 speed cassette that velo orange sells for this Group

I've put nearly 1000 miles on this shifter and matching derailleur, and everything works exactly as it should. Flawless shifts with Shimano XT 11-46 cassette. I initially wanted to buy full Shimano, but (because of VO's reputation) took chance on this Sensa gear, and absolutely no regrets, especially at the price.
