This wireless system is very easy to use. Im using it with my guitars when playing live and has never had any dropouts or other problems. The only gripe is that the intrument cable seems a little bit on the weak side and Im not sure how long it will last. Therefore I always have a backup cable laying around on stage. The connection seems to be mini xlr so replacement, IF it breaks should not be a problem. The sound quality is good and I cant hear any degradation of the signal. Due to its simplicity, you cant switch operation frequency and this could pose a problem if you get interference.
