I am using this pedal in my pedalboard primary for practicing. The pedal works great, it is well built and works without any issues. It works in three modes - standalone looper, drums accompaniment and looper synced with drums. The sync works well so when you record a loop, you don't have to press the footswitch exactly on the beat, if you will be close, it will work.
One think that does not work well for me is the tap tempo button. I am having problem to tap slow tempos, I think the rotary knob would be better. In addition, when you record a loop and you stop it by double tap (make a mistake for example) the tempo will be reset to default one so it is necessary to set it again.
Drum rhythms are good, they sounds well through the guitar amp. However, I would like if there would be more variations (currently there is 8 genres, 2 variations each) , sometime it is hard to find a good fit for a piece being practiced. Also a metronome would be nice.
Other that that - great a and super-simple pedal.
