Great in use!

I bought it for band practice and performances for the bass player and myself (guitar), with all the wires on the ground and the short distance with the cabel it's always looking where you are walking. But since we use these wireless modules it's very easy to walk around now. we checked the sound quality with a few good cabels and in presence sound engineers couldn't hear the the difference except for the louder volume (wich is understandable).

The only con we have is that the battery of the transmitter doesn't last as long as the battery of the receiver.

Great product, for a good price!
