Well, they seem a bit more user friendly than the Draco pistols. They are a neat range toy and conversation piece. Better for home defense than a Tec-9. That's about all the good things I can think of to say about them.

As for negatives, I've heard they tend to have reliability issues and it is only a matter of time before ATF bans them. They seem impractical to me for just about any purpose than looking cool, but I support the right of law abiding Americans to waste their money on anything they want. At an average starting price of $800 I don't see many falling into the hands of gang members.
