Not really one for reviews but I am really impressed by these. First the bad... They are so good looking that they make my pride and joy, built from scratch Alien 5 " Quad, look like its lacking. I mean that piece of hardware is my equivalent to the Jedi's Light Sabre and its now needing something to 'up' the game to compete with... props!? The good... They fly wonderfully. They sound better than my last brand (Steels not so favorite), they might have added over a minutes flight time (not completely sure about that but I think so). last thing, they appear to be tough as houses. Had a good smash into a metal pole today and barely a scratch... Odd, maybe just a lucky strike.
