I use it for my Nux LoopCore. It's a sturdy, small, compact footswitch that gets job done with some issues. There are three major points:
1. Before use get a decent stereo (TRS) patch cable to connect it with a looper pedal
2. It does not always respond to a tap (sometimes you change your solo and the loop phrase remains the same after a solid tap; could not figure out the reason, and it happens rarely)
3. If you want to go one phrase back you have to double-tap it (actually, that's the main concern regarding it's everyday use)
