TLDR: Pros: Complete kit, convenient, supports 3 people Cons: lock/key ambiguity This is a lock-out tag-out (LOTO) kit that contains 3 locks, each with a unique set of 2 keys, 3 clasps (two metal clasps of different sizes and one plastic), 20 LOTO tags, white cable ties, case and instructions. The case has a generous volume and easily fits all the contents. The case has Velcro straps on the back that make it easy to attach to a rail or bar. It also has a loop and could be hung from a hook or clipped onto something using a carabineer. The case has a clear plastic slot for an ID tag. There is also a small compartment labelled \"key\" but the set comes with 6 keys and I doubt that more than 2 could fit in at a time. Everything looks and feels reasonably sturdy and well made. The locks aren't designed to prevent bad actors from, for example, breaking into a locked shed. That is, they aren't replacements for standard pad-locks. The assumption is that the people that you are working with will respect your lock and not try to force it off, especially if you make it very inconvenient for them to do so. The locks have a plastic body with a solid metal hook and metal key mechanism. If someone wanted to bust them open they could do it with a little determination and strength; but if they did, they'd probably go after the clasps which would be easier to force open. Bottom line: don't buy the kit as a cheap way to get padlocks. The 20 tags are thicker than paper and much stronger. They could be used many times--but they aren't so nice that you'd feel bad throwing one away if you wrote on it. Each lock has a unique set of two keys so 3 different people can use the set at the same time. My only complaint is that all the keys and all the locks look alike so it isn't readily apparent which key set goes with which lock. When you open the kit for the first time each lock is in a box with it's own keys. I keep the keys in the locks when they are in the bag to make them easier to match
