Hannah R. ★★★★★

The metal body feels way sturdier than the plastic lockbox it replaced, and the Bluetooth unlock is surprisingly quick once you pair it. I keep spare keys inside for my dog walker and she loves not fumbling with a combo in the rain.

Michael R. ★★★★★

The fully removable shackle lets me secure my tool bag to a shelving unit at the job site easily. Bluetooth pairing was fast and the metal body feels tough enough for daily use.

Natalie ★★★★★

Gave this to my parents so I can let the dog walker in without handing out a house key, and the removable shackle makes it easy to loop around the porch railing. Unlocking it from my phone across town worked on the first try.
