oh no, I'm not asking bc I'm interested in buying.the only one i bought was a stealth but i was curious based on the reviews. i have seen numerous forum members, mainly builders, buying knock offs to see how they tickn to post reviews to why they are bad. so i figured if someone on here had some knowledge as to why they suck, more than the obvious reasons, it might make my co workers think twice bc they are more concerned with their wallets than their morals.
