    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.

    Works as intended. Love that it is rechargeable. You can manage access and give everyone a different pin or set a temporary one. You can set notifications when it unlocks or locks.

    The Effy deadbolt is a great convenance! It gives me the ability to program different codes for different people I want to have access to my house. It also lets me lock and unlock the door remotely. Don't forget to charge the battery!

    Install was very easy. Setup was super easy getting it on the eufy app and connected to Apple Home. I wish all the eufy products would be matter compatible because it works great. The only downside is I had to setup multiple fingerprints and pins through the eufy app. I think thats due to matter being so new and i didnt down the rating for that.

    There are multiple things to like about this replacement lock; installation took about 15 minutes, setup 5 min tops, integration with Apple Home zero problems. Set up finger print entry for my wife and I and she said she has had zero issues using her print. Also, I have multiple locks. Once my print was set up for one lock, it worked on the other two locks. Would definitely recommend.

    I have been happy with this lock so far. Install was pretty easy. You might need to drill the hole out more in your door jamb if it does not line up properly. The only issue I have had is when I linked it to my eero mess system it would lose connection about every 2 days. I then linked it directly to the router and had been fine ever since. It can be a little fussy on your finger print for unlocking the door. I found that if you just do 2 setting of your finger print it works fine almost every time now. You can unlock the door from the app and it also tells you who unlocks or locks the door. I think for the cost it’s a nice wifi lock.

    It's nice to come to the door with your hand full of groceries and not to have to reach in your pocket for keys and then find the right one. Just use your finger or punch in your code and the door unlocks. Easy installation, easy to use. It does require a Thread Border Security. Google Nest has it. It has a key backup and a battery that is suppose to last months.

    This lock has worked excellently and much better than the more expensive Yale lock that I returned. Fingerprint recognition is really fast and consistent. I like that the battery lasts a long time and is rechargagle.

    Works great. Fingerprint works flawlessly.I also like very much the auto lock feature where i can set a certain amount of time when the door will automatically lock after being unlocked. Works great with alexa. 5 stars. Would definitely buy again. I am going to buy another for the back door.

    It works great on my door and I love how it works with Apple Home. For the price I think it is a pretty good lock. Though I got it for sale for just over 130, probably wouldnt have done it for its full price. If you can get it on sale it’s totally worth not needing another key on your key chain and being able to give people temporary access.

    The difference between the E31 and the E30 is the fact that it has a rechargeable battery. But man, does it come in clutch. The rechargeable battery is a blue brick that can be recharged with a USB-C cable. I keep hearing that the E30 keeps getting blasted with negative reviews on the battery life, but this thing is rechargeable! Comes with ease of life features like code scrambling, a nice finger print sensor, and the ability to use it with your virtual assistant(s), such as Alexa or Apple Home/Siri. This does drain the heck outta your battery, but guess what? It's rechargeable! Only complaint is that it's not tactile and is a bit hard to see in the dark. But it keeps getting discounted and the pricing is really really nice.
