Review on 🔒 Puroma Stainless Shackle Storage with Packlock by Sri Mims

So I bought two of these padlocks and they look like standard disc locks and look decent. BUT. I went to have more copies made by a conscientious locksmith with years of experience and she told me that since they are made in China they need a special blank to copy. She managed to make 4 copies of the same lock and they all worked great. She then tried to make 4 copies for the 2nd lock. Copies sometimes worked, sometimes not for testing, then all together stopped working. The keys that came with it work perfectly. So something in the mechanism of Chinese production is not like American-made blanks.
