I bought it because of the price. I had one conflict with, of all things, the drummer using a wireless of a different make on his keytar (I know) which caused me to experience a weird lagging latency. He ent stright to the PA via cable and all was good.
Otherwise no issues at all. I like the size of the unit, I like being able to power off a 9v supply or a usb, I like being able to set it up for different basses and save the set ups, and I like the tuner.
