Customers are mixed about the quality of the lock. Some mention that it's a good smart lock with great options for door locking, such as finger print, keypad, physical key or via the App. However, others say that it is not a proper deadlock, slow sometimes, and the auto lock can also be problematic. Some customers also mention that the latch catches when locking or unlocking.

Well built,  but the locking/unlocking functions are currently unreliable

Well built, but the locking/unlocking functions are currently unreliable
I bought this door lock (from myanker.com.au) because I have other Eufy products and they're great quality. The build quality of this smart lock is excellent - it's really solid and seems well made - and it's great to have four ways to unlock it (pin, touch, key, phone). But I've had the lock for 24 hours now and I'm disappointed with what I assume are bugs in the software:1. When the lock was first setup the firmware update kept reporting it had failed. I retried, rebooted my phone etc and it always failed. I gave up. But sometime later I discovered that the firmware update seems to have been applied even though it reported a failure.2. The wifi connection from mobile phones to the lock keeps dropping (on both Android and iPhone). We have to turn off wifi on our phones and turn it back on again to get a connection to the lock.3. The autolock (that is supposed to automatically lock your door after the door is shut) sometimes stops working. To fix it I have to recalibrate the lock.4. After successfully setting up fingerprint recognistion for my wife and I yesterday, the lock failed to recognise our fingerprints today and we had to use a PIN to get in the house.In conclusion - it's built like a tank and has great features, but it's currently pretty flakey/unreliable. I hope that the firmware/software gets more reliable over time or I'll be returning this. I don't want a lock that doesn't reliably auto-lock or recognise our fingerprints.

Looked at a few options and selected this one.
All the access options work as they should.
Fits into existing door holes from the removed key lock.
The rechargeable lithium battery was easy to charge. Noted most other alternatives use AA batteries - no thanks.

The lock was simple to install for me. My door already had a manual dead-lock previous to my purchase so I did no need to cut any new holes. The Eufy just slotted right in easily and I have had no complaints from anyone in the house about using it ... that's my mark of success :). It can lock/unlock with a code (you can allocate a code for each person or for guests, cleaners etc. for use between specific times if necessary), you can lock/unlock with a finger-print or there's also a set of keys. You can also unlock/lock manually from inside and it will also lock automatically on a timer if you want it to. So far, I am very happy with this lock.

Swapped out for an old Samsung lock in no time. Great to be able to add the connected features. Easy to use and simple to setup. Fingerprint reader can be a little slow sometimes, and the auto lock can also be problematic but it will lock automatically after a few minutes anyway.

Great for a family that keeps forgetting their keys! Autolocking feature great for security. Took me a while to work out how to open the magnetic keyhole cover. Battery doesn't last as long as advertised before needing recharge but is still good. Occasionally the latch catches when locking or unlocking but I think that's more to do with the door than the lock. Finger print recognition is a little fiddly sometimes requiring moving the finger around to work.

We are all in with eufy, with the cameras anyway - and a cautionary tale to be told considering Eufy's user agreement fineprint. A yway, this integrates to the homebase really well.

The battery lasted about 3 months with 5 or 6 locks a week.

I installed it, replacing a door handle, and had to drill deeper into the frame for the bolt to fully engage. A pro would've done a neater job, so don't be cheap like me.
