Super Happy Camper
This door knob is the cats meow! I work nights and I got sooo tired of every morning when I got home and am so tired I'd forget to keep my keys in hand till I unlocked the old knob and would throw them in my big ol bag of crap to then get annoyed bc I had to then dig for them so I seen this knob and the price was right so I figured eh why not?! It was very easy to install with the instructions and video. Had it installed and registered with the app in less than half hr. Came with 2 reg keys n 2 fob cards. I haven't gotten the gateway yet but I really don't see a need for it right now. Finger unlock is my favorite, works awesome, fast and easy. I like how the app generators a code for u for pretty much anything either permanently, one time use, you can even schedule it for certain days and times many choices. I set mine to a certain code, every weekday at between 3-4p when my kid gets home from school just in case he forgets his fob at home (he's 11). My disabled mother lives with me and I registered her finger print with the app so now I don't ever have to worry of her getting locked outside. The app is easy to use and understand and can be linked with yr email and cell number... It's absolutely awesome 👍🏽👍🏽 I get in my house quicker then I did with old school 🗝️ will be buying more for the other doors in my house.

Pretty Easy to Install
First off, please realize that you will likely have to relocate your deadbolt (if you have a deadbolt). This is pretty common with these smart handle locks because they're so tall they would bump into the deadbolt if you tried to install in the normal place. So make sure you can work with that. I thought the instructions were pretty easy to follow. If you have zero experience installing a door knob, you should probably watch a Youtube or two first just to get how it's supposed to work. The lock looks very nice. I appreciate that the battery and everything is located inside the house. The keypad does read when I push on it so that's cool. I liked that there were many different options to access the lock so you don't always have to worry about having internet or a dead battery or remembering a code or having the physical key or keycard, etc. I will say that it's a struggle to get the fingerprint reader to read sometimes. I've added myself twice to the unit so it should have an even better chance at recognizing me but sometimes it does take 7 or 8 tries to get in. THAT SAID: the lock gets SUPER hot in the afternoon due to the setting sun and perhaps the heat makes it less accurate. It's possible that it would read the fingerprint better if it wasn't boiling hot. I DO like the keypad but....you have to know it's there. If you don't know it's there, you wouldn't be able to tell. It just looks like a blank door knob. So you have to poke the area the keypad is in before the numbers light up. THEN you can use the keypad. Not a big deal but I'm not sure it will work great if you had an AirBNB or something because guests might not intuitively understand that they need to touch the blank handle before the numbers will light up. I also think it's weird that you can't lock the handle from the inside. Like, there's no button to do that, apparently? And when you want to lock the door after you leave, you have to hit the * symbol on the keypad (or I believe you can lock it from the app) which is fine but not exactly intuitive. So, again, if you had AirBNB guests, they'd have to read your instructions to lock the door and we all know people struggle to read instructions...lol. There IS an autolock feature which is great if it's your house and just you and the fam come in and out. But if you have AirBNB guests, I don't think the autolock option is ok to leave on because guests aren't going to memorize their codes and what if they get locked outside without their phone? They'd have no way to figure out what the code is OR any way to contact you. However, I do really like the lock and all the features so I would recommend buying it and giving it a try. Just one thing to note for those who care: you don't need WiFi to set up or use this lock. It connects to your phone via Bluetooth and once it's set up, you don't even need Bluetooth. Just use the fingerprint or keypad or keycard, etc. I believe you can set up the lock to work with WiFi but I believe you'd have to purchase a second gateway or something and plug it into your house and I don't have internet so.... yeah.

Excellent Value packed with features
This was a great lock and I'll be getting more in the future. Easy to install and program. Worked great and comes with a key fob for easy opening. I bought this for my ski locker at a vacation rental of mine and I love being able to give my guest a key fob and passcode. Love having my finger print programmed so I don't have to worry about having a key on me. They also have a hard key back up in case the battery dies on you! It was easy to set it up and program it. Only drawback is if you want to access remotely you do need to pick up an additional gateway to connect to it, however at the price point this came in at I wouldn't have an issue picking up the gateway. Will pick up for future rentals

Decent smart door handle/lock
Seems to be working good so far. Set up was easy. Make sure you enter your finger print about 10 different times. Much better recognition success rate that way. The reason I dropped off 1 star was due to the fact the handle is only able to be pushed down. You can not raise the handle up to get in or out the door. Really weird if you’re in the habit of lifting your door handle up to open the door.

Couldn't be more impressed
⭐⭐⭐⭐⭐ I recently installed the electronic locking door handle in my home, and I couldn't be more impressed. This device has completely transformed the way I think about home security. Here are a few reasons why I highly recommend it: 1. **Convenience**: Gone are the days of fumbling for keys in my bag or pockets. With this electronic locking door handle, I simply enter my personalized code, and the door unlocks instantly. It's incredibly convenient, especially when my hands are full with groceries or bags. 2. **Security**: I feel much safer knowing that my door is equipped with an electronic lock. The advanced technology ensures that only those with the correct code can enter my home, providing an extra layer of security for my family and me. 3. **Customization**: I love that I can easily change the access code whenever I need to. Whether I want to grant temporary access to a guest or update the code for added security, it's a quick and simple process. Plus, I can even monitor who enters and exits my home by tracking the access codes used. 4. **Sleek Design**: The sleek and modern design of the electronic locking door handle adds a touch of sophistication to my home's exterior. It seamlessly blends in with the overall aesthetic while still standing out as a high-tech security feature. 5. **Reliability**: I've been using this electronic locking door handle for several months now, and it has never let me down. The build quality is top-notch, and I can always count on it to work smoothly, rain or shine. Overall, I couldn't be happier with my decision to invest in an electronic locking door handle. It has simplified my life, enhanced my home security, and added a modern touch to my entryway. I highly recommend it to anyone looking to upgrade their home security system.

Great functionality, app is a huge plus
Install was relatively easy and straight-forward. They have an app with step-by-step instructions as well as a paper manual. I programmed my fingerprint around 3 times and have not had any issues with getting in on the 1st try. I love the application functionality. Locks well, and you can also set an auto-lock timer which I liked. Quality seems great and so far we're really happy with the purchase.

Great to use for a business, easy to set up and clone to additional locks
I do I.T. work for a local business, and they wanted a better way to secure their doors inside the building. After doing some research and looking I came across these and decided to check it out. I got the first one installed, and it worked perfectly after getting it all set up. The fingerprint scanner worked, the code input worked, and the FOB worked, so there are multiple ways to enter using these methods. Once the owners saw that they worked well and were easy to use, we got 8 more for the business. They were super simple to set up, and the nicest thing about it, is I could tell it to clone all of the information from another lock, so I didn't have to manually set up each lock individually. The only thing it does not clone is the fingerprints, which I can understand, and those are super simple to add, just might take a while if you have multiple doors with this lock. It would be nice if they connected remotely by themselves, but they require a wireless HUB if you want to do that, so it's not a major downfall, especially for the price! Very easy to install, and easy to set up!

Great look, Easy Install
Appearance: I was so excited to receive this item and install it to finish up my game room look I was going for. I chose the gold look and upon review of the components, they were all good, no scratches or dents of any kind. The items felt good in the hand and not as if they were completely cheaply made. The handles had some weight to them. All in all I couldn’t wait for the install. Installation: I remembered there was a video of the installation of this product before I purchased it and that’s what I went off of. Made things super quick and simple and easy to follow. The one thing I’d recommend that should be mentioned in showed in the video is regarding the placement of the wired connection on the inner side as you connect the inner and outer pieces together. In the video it isn’t clear enough of how it’s placed and caused a minor hiccup in the installation as I had to find a place to put the connection to be able to push the inner piece to the mount to screw the outer piece in place. For me the rest of the process went smooth. I have 2 small concerned complaints: first is the door handles are tightened in place by a very small screw with a provided Allen wrench. We’ll see how well the screw holds up. Second: the cap covering the keyed access isn’t held on or tied on by anything so once the piece is removed it’s up to the user to put the piece back. In other words I feel it can be lost easily. In a way, it’s very easy to take them off and switch to other side if needed. After charging some batteries, installing the fully charged batteries, downloading the phone app (on iPhone 13 Pro), following the video to connect my locking device to the app was very simple and easy. I also tried the many other options (using keyed in codes on the keypad, fingerprints, included rf cards, and keys). Everything worked and went smooth. Tried the fingerprints the next day and all is well. This unit does speak (unlocked, locked, battery low, using keypad…and such). Not sure if this feature can be turned off but I like it so it stays on for me. Will update review if anything worthy to report. Overall Price: I feel the price may be a bit too high but according to other similar locking devices and the technology used, it’s acceptable.

Good when it worked.
When it works it is great, purchased in December but by Feb the lock did not always unlock. Not the batteries but the plastic plunger that activates the handle. Difficult to replace as it was over 30 days but managed in the end. Now on the second one so see if it’s a one off failure or a design fault.

Very easy to install and setup.
Easy to install and use, setup was a breeze. I added all fingerprints swiftly and it works flawlessly. Fits behind my screen door with no issues and looks very nice on my door. My one gripe was there is no QR code to download the app (have to search TT Lock on the store).

Too bulky compared to other smart lock
Too much bulky and we can’t lock the screen door. End up buying other smart door lock so better check the size.
