I was a bit reluctant, as the brand is relatively unknown, but decided to go for it due to the good reviews. The goose neck stays firm in place and the clip is secure on the rim of the sax's bell. The power module is quite heavy, so it's good having the belt clip, but wouldn't attach it to the sax in any case. Both adapter plug inputs on the module are very snug and it takes some effort to plug/unplug, but not really a problem.
The module connects directly to a console via an XLR cable and the sound is awesome at both scales. The only problem is that there is no led on the power module to indicate that the mic is on. In general, I am very satisfied from the quick delivery (thanks Thomann), the quality and the performance (despite the lack of the led). It's a full package, as long as you don't want to go fully cable-free, and at this price you also get phantom power, which is a huge bonus. I hope it lasts long.
