I wasn't sure what should be my first wireless kit and finally settled on this. A few gigs in and it's handled very well, with only one case of having cutouts and that seems because a crowd of people got in between, which is a shame but not the end. Fairly easy to use. Batteries seem to last a good long time.
Only thing I wish is that there were an easy way to provide wireless also to the main box itself and not run only off wall power. I have yet to have been given an option that didn't involve a car battery. I wish I could be completely wireless AND portable given my Bose S1 runs on battery. Wish it could also power this on the side.
