TRS is a good product I used for 1 year
but there is even a BIG PROBLEM!
If it fails, a direct buy back!
even if I find AudioPhony is a good brand, they have a shit Service
the microphone is sold on average 90 (with receiver) on the market. If your microwave does not fall down and you want to chage without changing the receiver, it will cost you 102 thus conclude their products are not overpriced pice but the parts are expensive
better to choose the vh Gmini 101 m it is guaranteed 3 years and it is better quality!
I use it for almost 8 years on an occasional basis.
He almost always worked well. It is economical with batteries. It is insensitive to feedback and parasites, has a good range even for fairly large rooms.
The only problem I had with it is a seam failure on the jack in the receiver box. A shot of the soldering iron and the case was settled.
The only criticism I would make is that it tends to saturate for use in concert. Except for the karaoke DJ or animation things are going very well.
