"great mid cap for anyone on a budget. no feeding issues as of now?

"I haven't had these too long, so I can't speak as to durability, but I mean, they're literally $10. They feel pretty sturdy, work really well with my M12 speedloader, and for the price, I can't really complain.

Value. $10 can't even get me a good bag of BBs.
Work Well (so far). Haven't had any issues with it, but if I do, I'm not going to break the bank getting a new one.
Disassembles Easily. If you get dirt in it, slide off the bottom plate and remove the spring and feeder. It's not easy to get back in (as with the springs on most midcaps), but if you really need to clean it, you can.

Plastic. Obviously, for $10, you won't get a metal one. The plastic doesn't feel all that cheap, either. So this isn't a con for anyone other than those "I purposely drop my magazines in dirt and off a two story balcony" people.
