    • Easy to use
Feels like good quality. We love the fact there’s multiple ways to unlock. You could use all fingers on both hands if you wanted to. So far the only problem is sometimes I have to have the smart lock read my finger 1-3 times before it actually unlocks and other times it gets it on the first try. The passcode and key card work great. I have had the smart lock installed without batteries for 2 months since I did not have WiFi. When I got WiFi I was able to completely set it up and so far the app has not given me any issues. The installation process was pretty straight forward but for some reason I’ve had issues on both doors trying to change out the plates into the door frame because the locks no longer went into the holes in the door frame after I changed them but that may just be the way my door frame is built lol. Would recommend to anyone who might be a little tired of struggling to find your keys while you have other things in your hands. Also to anyone who would like to know when a door gets unlocked. ... show more

    • Great value, excellent customer service
Color: Silver Size: Smart Lock
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. ... show more

    • Going Good - So Far
Color: Silver Size: Smart Lock
I purchased five of these locks a few months ago along with a Wi-Fi gateway – more on that later. As for the locks I have to say that I am impressed currently – who knows what the future holds. They arrived securely packaged and the installation was straight forward. I did have to chisel out a couple of the jam strike plate areas to allow for their proper placement. You do want to pay attention to step 4 in the installation guide regarding the location of the “▲”. But don’t worry if you mess it up just take the lock off and do it right this time! Setting things up can be a pain if you have multiple locks and need to get a bunch of people’s fingerprints registered separately on each lock. (Minor criticism) Here’s a tip: The fingerprint readers work well, but they’re sensitive to finger placement. Make sure your finger is positioned the same way each time you use it, especially as it was during registration. For example, if you reach for the handle and press your thumb differently than when you first registered it, the sensor may not recognize it. Only kind of grumble I have is regarding that same fingerprint sensor. If moisture is involved, I hope you remember your code or have a registered card with you. It’s not as bad as I made that sound but if your hands are wet or there’s moisture on the sensor it can be very particular about recognizing your fingerprint. I have used my code a few times because of that little issue. I was worried about battery life, but I can tell you that, after 3 months, two locks are still at 100%, while the other three show 95%. So, I guess we’re good to go there. Oh yeah, the gateway. The gateway’s only purpose is to provide remote access via the internet and/or integrate with smart home systems like Alexa. And there’s a little disappointment here as well. Yes - you can lock, unlock, and check the status of each lock via Alexa. But you can only do it one lock at a time. SIDENOTE: Alexa+ handles this better and will address multiple locks in the same request. P.S. These locks are NOT waterproof, they are water resistant – which means they might survive a heavy dew. The one lock I have that is exposed to the weather now sports an outdoor keypad cover, it just needed a little modification for the door handle. I can't rate them as five star, but I would give them 4 1/2 if I could. Yeah, I can recommend them - but don't come looking for me if your experience isn't the same :-) ... show more
