Great feature to be able to use when away

I am widowed and have three dogs. I woke up several mornings and realized I failed to lock up after one or all three dogs got me up to go outside during the night. We have had a crime spree (as has the rest of the country) and I had to figure out how to avoid this happening again. I did not want unwanted guests. I also had to figure out how to enable entry for someone, a trusted individual, to gain access to my home in the event I needed assistance or they needed to do a welfare check. This lock does it all. It automatically locks a few seconds after the door is shut. It automatically unlocks when I have my iPhone with me, to allow my entrance and then locks after entry and door is shut. If I need to let someone in the house for some reason, and I am not close to allow them, I can remotely enable entry.

Super easy to install. Installed 1 each on 2 locks. work great

I wish someone would have told me about the wifi problems with this cartridge. Even though I set up the door lock with 2.4G, my wifi keeps switching to 5G, which is draining the batteries on the lock, and disabling the lock. I have asked the wifi company to disable the 5G, but they are telling me this fix is only temporary. I am just crossing my fingers.

Cannot update the firmware of my lock nor connect with HomeKit. I have tried everything short of declaring this to be garbage. And it's not the only one I bought, thinking the first one was defective...
