I've used this one for the oast 2 years or so.
Pros:
Very comfortable headpeace. The sound is clear and of good quality.
Battery indicator on transmitter is a plus for me
The signal is strong and doesn't stop/break
Cons:
When the transmitter is turned of while PA isn't muted or turned off it, produces a very harsh and loud hiss/noise (maybe a factory fault)
When the mic has a bit more gain it feeds back a lot and is difficult to EQ or get rid of the feedback...
