You Pay For What You Get

For the price, the door's fingerprint feature works well. It can be a little unreliable at times, but you should always have a key or your phone as backup anyway. Overall, I'm really happy with it—definitely better than spending over $200, especially if you're just renting. It's provide ease of use when entering the house. Make me feel like my house is a smart home now.

Really easy to install and set up, love that I can give access to my kids and assign their name because I get an alert when they open the door. I not only know someone entered the house, but who.

Easy to install, directions are clear, fits existing door and simple download set up the password fingerprint. I bought one for my Grand Daughter's Dorm room she loves that it's keyless, but can use a key. Also, get phone notifications of entry attempts.
