I wanted to try this wireless since it doesn't operate on the wifi 2,4ghz frequency. This is the first time I've used a wireless that doesn't have dropouts.
I've used it for 4 gigs now, and tried it with my acoustic, thru my helix and even with an ukulele. No dropouts!
The battery didn't die even on my longest gig where I used it (3-4 hours of playing).
The only negative thing I have to say about it is that it feels very cheap and plasticy, but if mine every breaks its price makes it easy to replace.
