The Stealth, at least the older unit, is garbage. That's first-hand experience, not some "friend" telling me.
I was being facetious. I know the original Stealth was junk, and I didn't even have to buy one. I use Sennheiser wireless systems for everything.
I imagine that Mix's conversation with his friends went something like this:
Mix: How's that Stealth wireless system that you bought?
Friend: Works great... no problems. You should buy MINE!
