The Thermolds might fit the bill for being disposable (like a Bic lighter) and I thought these polymer mags were more like Zippo lighters (terrible analogy perhaps, but it's clicking with me so I'll run with it). If that's the case, that these ARE meant to be low-cost, low performance, so be it.

This has been informative, I appreciate the constructive input!
I just sold the last thermolds i have had since 1998. Only issue i had was having enough on hand to sell for a 'reasonable" price to other shooters. if you're concerned about reliability NEVER buy USED USGI mags with black followers.
All mags have some quirks. The last batch of gen 2 pmags don't lock in to ANY AR i have. Sending them back was not an option, so i fixed the mag release cutout area, to have them function.
