I have one and love it. It is, shall we say, unique.... It is expensive to feed and ammo is scarce right now. However the patent on the ammo just ran out, so hopefully it will be available in bulk.
Overall, it is a blast to shoot. I love it for home defense (yeah, save the lecture on over-penetration) because its 50 flat shooting rounds trumps most anything else that may get carried in the house.
I've done 1200-1500 rounds without a single hiccup. Ever. It's also very clean shooting and cleaning usually requires nothing more than a bore snake.
I out an Eotech on mine and it is just great.
Again, it's expensive to shoot. 50 rounds will last around 30-40 seconds and cost $25... It's more expensive than a Vegas Hooker to play with a night.
