Bests & Worsts Reviews from Amazon

I ordered these locks so that I could practice my lockpicking hobby (Master brand locks are among the least secure), and for that they worked wonderfully! If you're a beginner, these are for you :) If you are just wanting to buy locks to lock things, do NOT buy these. Here are the two biggest flaws: 1. They unlock themselves if you breathe on them. Attached is a video of me unlocking all three with one pick in 30 seconds (just a few minutes after receiving them). An ambitious kid could easily get these open with a hairpin, no special tools required. If you're going to the trouble of buying a lock, you may as well get one that locks things up. I would have made a video of that for dramatic effect if I owned a hairpin :p 2. Not enough keys. I saw in many reviews that some people only received one or two keys for their three locks. This is because of the packaging, the keys are easily able to just slide out of it. You may end up with only one or no keys due to this and have to return them. However this isn't an issue if you own a hairpin :p
