I had a trusty Nady UHF system that was just getting worn out that I wanted to replace. It seems like most of the wireless systems on the market today are 2.4ghz wireless, which I have remained skeptical of. I have always used UHF and it has rarely had any issues at the small venues my band plays at. I bought a 2.4ghz system just to try out for practice and the dropouts and loss of connection were a non-starter for me. I only dipped my toe into an inexpensive system, but it wasn't enough to quell my concerns with the system, especially since most venues would have multiple 2.4ghz wifi access points, not to mention the dozens of cell phones in pockets interacting with that signal.This UHF system reassured me that I'm still firmly in the UHF corner of devices when it comes to playing these venues. The signal is great, even out of line of site if needed. Outdoors is also not a problem, since we have a pretty even mixture of indoor and outdoor venues. The fact that I can have a handfull of rechargeable AA batteries and play all night is also an extremely valuable plus. 9v batteries can get expensive to replace before every show, and built-in lithium batteries are just a huge red flag for me in case the system dies in the middle of a show. Wish this would have had diversity, but that's about my only complaint.
