    • Works great, great software, fairly easy to install, depending on the lock
Works great, great software, fairly easy to install, depending on the lock. Has trouble locking if deadbolt has much resistance. I fixed ours by grinding the forward edge of the bolt to taper slightly. We own three of these on two different houses plus an Eufy video doorbell and they are all controlled by a single app. Batteries last a decent length of time (about 3-9 months depending on frequency of use), even if using rechargeable a23 batteries (which aren't much more expensive than non rechargeable ones). ... show more

    • Not reliable
Installation was easy enough. Build quality of the lock and keypad is great. The positives stop there. The app is terrible. I’ll go to lock/unlock my door using the app, and it takes at a minimum 45 seconds to a full minute and a half to actually do what I told it to do in the app. Sometimes it doesn’t work at all and the app gives me an error. I bought the lock so I wouldn’t have to fumble with my keys when bringing up groceries/bulky items to my apartment. I found that even with this lock, I still have to dig out my key to unlock the door since the app usually throws an error message or the lock is taking way too long to unlock my door. If I have to do that I might as well just keep the old lock and save the $90. Also the keypad I received with my unit doesn’t work at all. I tried different batteries and still doesn’t work so I’m left with using the poorly made app if I want to use the smart features of this lock. Another major issue, when I was at work, the lock unlocked itself. The app wasn’t running on my phone at the time and I’m the only one with access to the app, so how did that happen. Of course, when I went into the app I couldn’t lock my door due to another vague error. I had to go back home to re lock my door and remove the batteries out of the lock. Buyer beware. Don’t buy this one. There’s many other good options out there. ... show more

    • Works great
Easy to set up and works great. Nice feature to schedule a code for cleaners for specific days in the week. Had an issue at first where my code did not work, but sense then it has worked fine. I have been using it for a few weeks now and no complaints. Warning: bought two of these and the batteries died on both in about two months. So I’d recommend buying better/rechargeable batteries. ... show more

    • Generally good, some lacking features
Updated: The lock is nice looking and easy to install. I like integration with the doorbell. The keypad (mine is non-fingerprint) works reliably and quickly. I do not yet have battery life estimates. The first lock I received had extremely slow wifi operation: at least 25 second wait (unless very recently operated). Sometimes it would error out after a minute. I returned the lock and got the second one. This one works well, about 5 seconds for the "cold" lock/unlock. There are some areas for improvement: 1) Bluetooth on the phone is not used if wifi is available. It may be better for bluetooth to have a priority - it would probably result in faster operation and longer battery life. 2) At least for now there is no "auto-unlock when arriving home" on Android. On the other hand, maybe this is good - eufy app geofencing seems to kill the battery (much faster than other geofencing apps). 3) There is no "door closed/ajar" sensor. Some competitors have it and it's a very nice feature. But that's not a software feature, so it would require a new model. ... show more

I installed this lock in about 10 minutes it was easy to install in the directions are very straightforward. It works just as it should have had no issues with it thus far. The package arrived on time everything was included. I'm not sure how the battery life will last 365 days and I'm sure it won't based on other reviews so I will buy some rechargeable 3 volt batteries. The unit requires four of those and the keypad requires two AA. It's a very clean look and seems to be pretty durable. My main reason for purchasing is people tend to forget to lock the door around here and I aim to put a stop to it. Nobody on the outside with no any different that the lock is installed if you do not put the keypad outside. It's perfect for my apartment I technically didn't change the locks the landlord can still access the apartment with the original key I was given on my lease, and I have the security and comfort of knowing the door is locked. Being able to remotely lock it is the best feature I think it comes with. You can set different pins for different people so you know who is coming and going. ... show more
