I bought this set not to serve micro diversity animation for clients.
I already sm58, AKG D5, AKG C535 (my favorite) wireframe.

The pickups are very plastic, lightweight and hold well in hand. receiver seems stronger because metal and well finished.
The sound is very good, in line with the AKG microphone, ie with a good definition.
on the other hand towards a wired microphone you lose momentum. the sound "cup" faster.
Nothing alarming but obvious.
I feel this is not a Sennheiser EW100 which is not at all the same price, it is true.

For:

Price / performance / reliability
Very good sound, suitable for singing
Actual battery life very long stick with a simple battery
Good RF reception at 100m without diversity

Against:

Plastic finish microphones, closing the lid stack microphones sobering.
Dynamic compaction of microphones
