Favorite wireless I've ever owned. Love these things, but I don't play out anymore. Old school UHF in a compact format - no digital drop outs!
Only thing wrong with it is the little clip that holds the battery door closed is long gone. If you plan to always use the adapter instead of battery, i would just glue it shut with a tiny drop of super glue - but otherwise it's just a very minor annoyance. All works great.
