Wich one is the best c-mag/mosquito drum out there for a G36/MG36 ?
 

From what I've seen around the forum, most people seem to like the sound activated electric winding system althought I have no clear answer on wich brand. Also, there seems to me a limited knowledge of this winding system STAR 2500rd S-MAG wich seems to be a relatively new spring tension sensor system.

Any thoughts or experiences to share ?

EDIT: Seems the Star s-mag has been around a while so it's nothing new. I did find good reviews of it but they don't compare it to others. Also, is there any other brand making a similar winding system ?
