Eufy Security S231 Smart Deadbolt Lock Touch Keypad / Build-in WiFi / Fingerprint / Bluetooth / Weatherproof / 365-Day Battery Life

The fingerprint sensor is absurdly fast, never have to do multiple attempts. Just touch your finger and it immediately responds. This really reduces the hassle of entering your house. I cannot convey how much of a convenience this is. Installation was straightforward as well.

On the app side, setup was easy. In-built WiFi is great. But notifications are a hit and miss. Sometimes you get false warnings that the lock didn't properly close. At the least the logs are accurate when you are reviewing them. What I find odd is that you can completely wipe the lock just by having access to the QR code on the back of the lock, it doesn't even give a...view more The fingerprint sensor is absurdly fast, never have to do multiple attempts.

Could be a security flaw.
Battery is nowhere close to 365 days, lasting us only 8 months. The lock is only used 2 times a day, 6 days a weeek. The real issue is the fact that the rechargeable battery pack charges via micro-usb, which is a very slow charge time leaving your lock inoperable for over 5 hours.

Overall some teething issues and minor flaws for an otherwise good smart lock. Though I would keep my eye out for the new version with a camera in-built as well 'Video Smart Lock'.

Great product and works as stated other than getting the fingerprint to work everytime. Otherwise mo issues and love the fact it has 5 precut keys Great product and works as stated other than getting the fingerprint to work everytime. Otherwise mo issues and love the fact it has 5 precut keys

An easy to install and use door lock. It looks smart too and not too bulky like the other smart door locks.
It has all the functionality I was looking for (fingerprint, code or key option) An easy to install and use door lock. It looks smart too and not too bulky like the other smart door locks.

We have some people that struggle with technology and some people that forget keys or lose them. This takes care of all of them.

You can use a finger print or a pin code, or app to unlock the door. Worst case a key. It will lock the door if you forget after a few minutes or you can ask google etc if it is locked so no more "Did I remember to lock the door?" It just makes things easier.

It's easy to set up and integrates with the Eufy Home hub and door bell/camera etc. The battery lasts a few months but they never last as long as the manufacturer quotes.

Definitely would buy again.

I won't come up as a verified purchaser as I bought it...view more We have some people that struggle with technology and some people that forget keys or lose them. This takes care of all of them.

Really Smart :) Really Smart :)

Never have to worry about the cost and hassle of renewing physical keys. Now I can add my guests fingerprint and custom PIN then remove in no time. Also keeps track of who's coming and going since my property has multiple rooms. I do have two complaints however, 1 is that the battery life is rather short and the app is not super friendly. It maybe because of the number of people coming and going but the battery has lasted for 3 months which is not even half of the product claim.
