Guy in the video, fired about 100 rounds. He didn't even smile. If the guy selling the thing, isn't even enjoying it....
I can't see that the fun factor would be worth the intial cost of the gun, forget about the recurring cost of ammo. Not to mention, where do you use something like that. Unless you're testing police response times, you're not going to use it at home (urban areas anyway, where 90% of Canada lives). And if I'm at the range, I like blowing stuff up, which this gun doesn't do.
It's not a replica, as to be a replica it has to look like something. Even Hi-Points look nicer than this thing. I think it's pug fugly looks are just to ensure it's not classed as a replica.
I'd love it if a friend were to purchase one, hand me a magazine, and tell me to let'er rip. Aside from that, I don't see me ever buying or even using one of these, and I'm okay with that.
