works great thus far
this has worked great for me thus far. i bought it to use in the Master Lock w/ Adjustable Shackle and the fit is excellent. hasn’t budged and the retraction has been smooth and easy. unless something happens with it in the near future i say it’s a good buy!

Attached to the lock box next to the exterior door. Guest have no longer accidentally take or miss place the exterior door keys.

Perfect way to keep key with lock box!
Needed a way to make sure the key didn’t get dropped from the lock box and end up under the deck, or walk away. The bond is strong, and key pulls easily from the lock box to open the door. Perfect!

Love this..
I didn't want the key being misplaced by the workmen coming in and out of the property. It works great now if I could just get them to lock the lockbox!! haha

No allen wrench or tool to loosen and tighten the loop?
Does not seem to include the allen wrench or tool to open the loop, put the key and tighten the loop. Why would they not include that?

Switch out tape with stronger adhesive
This works great for what I needed but the double sided tape provided is not strong enough. I swapped it out for gorilla tape.

Not compatible with master lock
Bought a master lock key box specifically so I could use this. Only it doesn’t fit inside !

A great piece of mind
A great peace of mind. Easy to set up and install. Now I don’t have to worry about a key accidentally going missing from my lockbox. Worth it!
