Review on Industrial Safety TRADESAFE Lockout Tagout Kit Refill - 7 Keyed Differently Red Safety Padlocks, 1 Key Per Lock, Guaranteed Lock Out Tag Out Security - Trustworthy Lockout Tagout Brand And Company by Lacueva Tranquillity

I am very pleased with these locks. First, you should know that I use these to practicing lockpicking, not for their intended LOTO function. But for locksporting, these are great. The build quality is quite nice overall. Just as the ABUS 71/40, these can be disassembled non-destructively. The core is installed very securely and unlike the Masterlock 410, it doesn't jiggle around. Also unlike the 410, it has a flat bottom and can stand up on its own.The keyway is far easier to access than either the Masterlock 410 or Abus 71/40. Don't let that fool you though, these are still a challenge to pick. Tensioning from the top is a bit tricky due to the width and close proximity of the first pin. It can certainly be done, but the wrench tends to slip out easily. I haven't yet disassembled any of these, but I am certain there are some spools. I didn't feel any serrated pins, but I'm unsure of that. Just like the 410 and 71/40, these locks have 6 pins. I included a picture of the keys in the set I received. One in particular is very nasty and I have yet to successfully pick that guy. It will probably be a good long while before I open up number 02135 without a key.I like that these are available in different colors. It is nice to differentiate between my other locks. The pictures that I took don't show it, but these did have a sticker on both sides. One side is like it's shown in the listing's picture, the "locked out, do not remove" stuff. The other side has four lines where you could write stuff on them, and a "property of" at the top. Each lock and corresponding key both have the same unique number printed on them to make keeping track of everything easier. One thing to note however, the number on the lock body is laser printed. The listing's pictures make it appear as though the number is physically cut into the plastic. It's not a big deal to me as the picture does indeed say it's printed on. And it seems to be durable enough to hold up. Scratching at it doesn't really affect it.
