I bought this pedal after considering all the lower-end wireless transmitters for instruments, as it seemed the best compromise - a bit more expensive than the XVive system (which a friend is really happy with) but more features.
It does not disappoint! First thing I noticed was the weight of the pedal - it's built really well. Then the transmitter has a cable and belt clip if you don't want to hook it straight to the instrument - handy! Mainly, the transmitter has a *replaceable* lithium-ion battery, so you're not chucking the unit in 5 years time because the built-in battery is shagged. This is excellent!
Plugged in and played, the pedal receiver detected the transmitter immediately, no issue there. For me it's completely indiscernable from using a cable, quality wise - certainly in a practice/gig setting, I'd probably cable up to record anyway. No issues, no cutting out, no interference, just works.
The pedal itself is a tiny bit complicated, just because it's packed with options and has a limited interface (it's a pedal!) but it was still dead easy to figure out. I really can't fault this pedal set, I'm delighted with it.
