Review: Good product - Installs easy for the most part. They send extra screws shich is nice since the ones that came with it arent long enough but the extra (1) did fit . fortunately I have a selection of machine bolts etc.So long story short decent unit for the price. Do not install it without some protection from the elements,
Review: 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.

### ⭐⭐⭐⭐⭐ Great value, excellent customer service
*by T***E on August 8, 2023*

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.
