I've got an old TT bike that I use on my trainer and was thinking of converting to 1 X wireless with Sensah. Just watched a few videos on Sensah Empire kit and very few complaints. Certainly sounds like good bang for your buck. Lots of positive reviews on various bike/MTB forums. Not as smooth as Shimano, but at a fraction of the price. Perfect for converting an older bike to electronic.

From what I've read, Shimano/Campag etc have a ton of groupset patents which Sensah have pretty much ignored. So I guess you could call it Shimano knock-offs?

Former SRAM guys made Sensah. (hence the front shifting :D :D :D )

I've got two sets of road 11x, one with the big fancy Oversized pulley. It's hard to say if you'll "like" how it shifts / feels / etc... just subjective. But it is a competent groupset from a mechanical perspective.

*the decals on the derailleur literally came off as soon as I touched it (good thing, bad thing?)
