I was very happy that this switch was created. I need to adjust the volume while playing and this switch allows you to connect a volume pedal. Unfortunately, it has to be paired every time it is turned on. I could still survive that. But after a while of use, the switch stops switching, for example, 3 buttons light up at the same time, or they all go out,... A disaster for live playing. I waited half a year for a new firmware update, but it obviously didn't solve the problem. I have 2 switches and 2 Spar EDGE and Spark Live combos
