Great product
Purchased this smart lock about a year ago and have not experienced any problems. Easy to install and setup in the app. You can set different pins with allowed date/time of when those user pins can work. You can also lock or unlock when away from your home. I haven’t tried the fingerprint feature since I’m not a fan of it but is nice to have as an alternative. Battery life… boy… I forgot when was last I charged this thing lol

Great Smart Lock for Easy Keyless Entry
I’m really happy with this Eufy smart lock (E31). Installation was way easier than I thought it would be. Everything fit right into place with my existing deadbolt. The black finish looks nice and modern against my door. I did notice my handle is still silver, so I’ll swap that out soon to match. But as far as the lock itself, it works perfectly. I use the fingerprint reader most of the time and it’s quick and reliable. The app was simple to connect and I like being able to unlock from my phone when I’m heading home and my guests are already at the door. Overall, definitely worth it if you’re looking for a keyless lock that’s easy to install and looks good. Very happy with this buy!

Overall Really Great Smart Lock!
Upgraded to this lock from an August Smart lock. I am really enjoying the convenience of the fingerprint sensor. It claims an 18-month battery life, so we'll see how that goes, but the battery is rechargeable, so there is no real additional cost there. Beats the expensive CR123 cells the august used to burn through every couple of months. The only thing i would like to see in a future model is a more standard key way that can be Rekeyed to match the old deadbolt. With this lock, you have to use the keys that Eufy provides, which is a little thicker and can't be used in my other deadbolts. Overall, I would highly recommend this lock because it works great with both out goofle home and apple homekit set up.
