I disagree with some of the others comments on the drum, and agree with others -
First - the snap cover does break easily - but, thats nothing you can't fix with a thick elastic band, so I don't see that as a problem. They reload very quickly and easily.
Second - the spring didn't go so easily for me, I screwed it up once, rewound it (with difficulty and persistence). They also jam here and there if you're too quick on the trigger.
Last - There is nothing quite lick banging of 50 shells in a row just for the hell of it!
While I wouldn't say that the drum is the best made product I've seen, I still like mine. I only own one (and wouldn't have two) but if broke, I'd probably replace it.
Just my opinion.
