Works great. The auto sync mode is very useful. The small "mode" button is a little difficult to control but manageable once you get the technique down. I notice that when I stop and clear the memory (double click and hold) there is a small 1/2 second start to play the loop again before it is cleared. In a live situation this would be very annoying and shouldn't be that way. It would be nice if I didn't have to unplug it to turn it off, perhaps a switch or auto off after no activity
