This lock is great. Super easy to install and set up. Once you download the app, everything is right there to add user codes and/or fingerprints. I love the safety feature that if 3 invalid attempts are made, it locks out completely and only the admin (user of the app) can unlock it through said app. It looks very high end and love that the key lock is hidden by the fingerprint. I purchased this one after a well known lock brand smart lock I had just stopped working on us one day; and it was less than 2 years old.We installed this had a little trouble on our end but we were able to contact support and they walked us through every step of the way even sent us videos demonstrating troubleshooting via WhatsApp. I'm so happy that I bought this lock. It's working great will probably review later as I get used to using it. Just a great experience with contacting support. Thank you to whomever took the time from geeksmart to walk me thru this the other evening!!Love this lock! My whole family can access the house without the need for keysI recently installed this deadbolt because of how much I liked the similar doorknob by Geeksmart. I really like the looks of this. It was really easy to install (though I did loosen and reinstall it because I realized the interior portion was crooked on my first try. Even so, it only took 20 minutes tops). It is easy to lock and has a number of options that I'm still deciding which to implement. It has an "autolock" after a designated amount of time that I use for our doorknob but haven't here since the door is sometimes left open. The default for it was a max of 60 seconds but I realized I could make it a custom time of 400 seconds which is helpful. I was also impressed that it alerts you with a sound if the deadbolt tries to lock but can't extend all the way. The fingerprints are super handy but we did have one incident when my child came home and was locked out because her fingerprint didn't register. I'm hoping these are similar to the iphone where they improve their reading each time it's unlocked with that finger but we're also making sure to have a code that people know so they don't have to rely on the fingerprint. I'll update the score after we've had it longer and know if that was a one-time issue or a frequent occurrence (it would be 5 stars if it hadn't happened).This is a high-quality lock. It’s heavy, metal, well packaged, and has a clear instruction booklet and templatesEasy to install. Works great.
