This review is for if you are planning to use it outdoors.We have had SUCH a frustrating experience with this Igloo lock. We are now on our third lock in less than a year and second silicone cover that the company had to send us to replace them because they didn’t work. We’ve bought too many batteries to count bc they have to be changed every 2 weeks. We had been so hopeful that the silicone covers would work and sadly they did not. In this last attempt, even with a new battery, nothing would open it. We tried changing the passcode and the app kept saying it wasn’t connected. Bolt cutters would not get it off. My husband ended up hammering it to death and by luck it opened. We finally just tossed all three into the trash. I’m sure for indoors it’s fine but for outdoors it doesn’t seem to be able to handle the elements even with this sleeve.
