Keyless Entry Fingerprint Digital Smart Lock with Handle & Keypad: Electronic/Electric Lock with Code, App Control Biometric Deadbolt Door Knob for Front, Interior, Exterior & Bedroom Door (Silver)

I am very happy with this lock. The biometric feature lets me add family members that don't live with me, as well as being able to unlock the door through the app on my phone in addition to generating a one-time passcode if needed.I had someone help with the initial installation as boring holes through an existing doorframe just wasn't part of my skillset. I had the lock for a year and a few months before it started having issues; it gave a notification that the batteries were low, so I replaced them, and within 2 days they were low again. I used the same batteries on another device that worked fine, but in any case, I bought more expensive batteries and got the same result. I contacted Sifely customer service and they were terrific. I wasn't sure if my unit was even still under warranty and they never made a hassle about it--asked me for some additional info, then my order number from Amazon, and I received a new lock for free the next day. Installing it was a breeze and the company followed up with me to make sure everything was working ok. You really can't ask for better customer service.As to the lock itself, my only complaint is that the biometric sensor doesn't work well when there's moisture in the air (my door is recessed and covered by a screen door, so it's not getting soaking wet). Nevertheless, the keypad works in wet weather and that's all I need. Highly recommend for the price and convenience.

This is a solid door handle and mechanism. The only FYI is to be careful if you remove the small physical key cover. Four tiny magnets hold it in. It's probably hard to lose them, but mine came out, and I pushed them back in; it's all fine. The fingerprint feature works excellently, the app is good, and the push button entry works, too. It is installed on an exterior door to a pool house and, in the summer, is unlocked daily. I would buy it again no problem.

I have been absolutely blown away by the Dermum Smart Lock! This is a fantastic product that has exceeded all of my expectations. It works flawlessly every single time without fail, making it an essential addition to my home security. Not only is this lock incredibly effective, but it's also incredibly easy to use. The keyless entry system is a game-changer, providing me with the peace of mind knowing that my home is safe and secure at all times. Plus, the sleek design is a real eye-catcher and looks fantastic on my Work Office Door. What really sets this lock apart from the competition is the sheer quality of the product. It's clear that Dermum has gone the extra mile to create a lock that is both durable and reliable. I have complete faith in this lock, knowing that it will continue to provide top-notch performance for years to come. Overall, I couldn't be happier with my purchase of the Dermum Smart Lock. It's an exceptional product that I would highly recommend to anyone in the market for a reliable and effective smart lock. If you want to ensure the safety of your home without sacrificing style, this is the lock for you!

Takes some time to set up the features but overall satisfied. The finger print option doesn't always work on the first attempt. I am happy with all the extra features such as granting temporary access, pin pad, ability to set lock time, physical keys, fob and offsite lock/unlock capabilities thru the app. I installed on a preexisting door with no problems and it cleared all the extra trim. The online step by step instructions were super easy to follow however we're slightly different than the model I had. Anyone with critical thinking skills could figure it out. The handle seems little light weight compared to the rest of the unit. Don't think it will be a problelm with long term regular use.

Lock works very well, was very easy to install and setup, whether using touch, fingerprint or the app it works well. Had an issue with the lock months into owning it and customer service was excellent and took care of my issue quickly.

Update -- I bought a second one against my better judgement and it doesn't work. The screws stripped out and it became a huge pain in the ass to uninstall.The problem isn't with the lock itself since the functions (minus the fingerprint reader) works great. The problem is where the override lock button is located. Eventually I'll buy a different lock and move this one somewhere else, but for now it works and is a good price.Override Lock FunctionThere is a tiny switch on the front of the knob on the house side that clicks on and off to allow you to override the other features so no one can enter the house even with a code or fingerprint assigned. However, it is in a terrible spot. If you hold onto the door and shut it as you're leaving the chances of brushing against it and triggering it and locking yourself out are VERY high. Ask me how I know. :)Anyway, if you're careful of that, you can avoid it. The second issue is my dogs have triggered the button twice now as well. It was solved with a dog gate but if you have this in an area where you can't have a dog gate and your dogs can reach the lock, you can be easily locked out.Having a function where you had to press the button down and move it in the opposite direction it was currently set might fix the issue, but I think the answer is to totally move the button to the very bottom of the unit.Fingerprint ReaderSimply does not work. I have tried to register a few different fingers and done it a few different times but it never works after the initial first time setting it up.
