Crappy parts store voltage regulators

I just had a regulator meltdown myself and I swear to goodness it was the one that I paid extra money for to make sure it was made in America and I had it for a while and it's been giving me trouble. Anyways I've been having some trouble with it lately way over charging and the only one I could get was a standard. It clearly said made in China on the back and I was like oh my goodness!! for whatever reason I couldn't have gotten luckier and it's not going over 14.2...
Trust me I'm keeping an eye on it...
