Superior quality, pity about the battery life
A very good unit. No drop outs yet. Easy to use and quick to setup. My only gripe is the battery life. But I reckon most wireless systems suffer from this issue.

The best overall wireless model & brand there is.
I've been owning a G50 for years now & I love the simplicity of it & its form factor that seems the most appealing & most functional as well compared to other brands & models. So when I decided to build my first rack system, an upgrade to the top-of-the-line G90 was only natural.
Perfect wireless system!
Only one thing - i have to choise channels manualy. Because sometimes is too much wireless devices on stage and they disturb themselfs. But it works! Much better then AKG!
