I bought this product in order to store a number of keys for our office, which has a number of filing cabinets and storage lockers holding confidential information. I like the design, which is sturdy, and it allows control over who access the keys and when they do so. The key capacity is great, because we need to keep a number of keys sorted, and it is very clear when a key is in use or missing from the cabinet, which is important for security purposes. I also like that it came with number labels and stickers so that I could easily label and identify which cabinet eacg key went to.
