TCL D1 Pro Palm Vein Smart Lock, Keyless Entry Door Lock, Upgraded Rechargeable Battery, Front Door Smart deadboalt, App Remote Control, Auto-Lock, Waterproof, Works with Alexa

I have had this Lock for over 4 month and and extreamly happy with the product. It was easy to operat and works every time unlocking the door with my palm. I use it with Alexa and it will open with my number code from anywhere in the house to let someone in at the front door. I love I when I go to bed and am not sure I locked the front door and instead of geting up and going to check the dooor I just say "Alexa lock the front, and Alexa saya," Locking, hang on" and then Alexa say to me "Locked" I am almost 80 and appreciate that option. Very quality look and feel to the unit and it fit my front door perfectly. Has a secure look and feel to it. Excellant product. Very very highly recomend it for a very quality and nice looking instaliation!

I had a fingerprint reader lock but both my son and wife have very faint fingerprints so can't reliably get the lock to work. It also won't read my print when my hands are wet. In my wife's case, her fingerprint is so bad that even top end readers on Apple and Samsung devices can't read it. This lock solves the problem, and it works reliably even with my 8 y.o. son's little palm. So yes, the palm reader works, and works surprisingly well. The rest of the lock is pretty standard smart lock stuff, with the built in Wi-Fi a nice touch. I saw several reviewers complain about the app, but I already use the Tuyab smart app for smart switches in my home, so I liked not having to install yet another app. I find the pairing and set up process pretty straightforward and simple. Notifications to my phone work without problems, but I wished the notification would say which palm was used to open the lock. Overall, if you want a touchless smart lock, and don't need additional features like cameras, this work really well at a very good price.

Stay away,I bought this lock 7 months ago, 1st the palm reader stopped working and now it unlocks on its on and locks on its own, has a mind of its own, very scary equipment. When you open the door with the knob, it automatically on its own locks right before you shut it and then hits the deadbolt. This was a huge problem....Update, bought this lock like 8 months ago and I left a bad review, Well they saw the review and sent me a new one with no hassle, my suprise.O just installed the new one and im happy it is working as it should and time will tell.

Happy with my new high tech door lock and I'm even happier that I tackled the instalation by myself. It was fairly simple even for a newbie at this there was no need for any modifications. At fost the guidelines scared me a bit because it had some instructions to drill new holes but luckily everything was the same as my old one. I didn't even have to change the strike plate or faceplate. Took me about 30 minutes to swap from the old to the new one and then another 10 minutes to program the palm prints and cards. The app made it easy to do. I do carry the card with me but never use it since the palm print makes it so much easier. I added the prints of all my family and I like that in the history tab of the app I can see who and when entered. Another bonus is the rechargeable batteries which will probably last a while. After nearly a month of use, the battery is still at 100%. It works flawlessly with the palm print, but there is also the option for a code, card or key but I don't see myself using those often because, well, it's not as practical

This is a very cool lock that is functional and offers a lot of features. BUT, build quality is mediocre. The deadbolt seems flimsy and it is now slightly bent after less than a year of use. The lock gets stuck and doesn't open or lock properly all the time. I have to fiddle around with it a bit to get it to work properly. The app only worked for a month before it randomly stopped and I was never able to connect the lock to that app again. Install was easy enough and required no modifications to my current setup. But I would not recommend it to anyone because when I reached out to customer support for some answers, they ghosted me after one reply. It's disappointing because TCL is not just a small company with one product on the market. It's a well established brand and yet they can't stand behind their product. I'll be changing my lock to something else shorty. It's a solid DO NOT BUY from me.

This lock is a powerhouse. While other brands charge more for fewer features, the TCL D1 gives you everything in one sleek package: fingerprint, palm vein, passcode, key, app unlock, remote control, even two-way calling and live viewing. The palm vein scanner is lightning-fast and flawless, and the adjustable camera lens is crystal clear. Setup was a breeze. Super easy install, no wires, rechargeable battery, plus a backup external charging port. Customizable motion detection and cloud storage options make it even more versatile. Now the downsides…Battery life isn’t the best and once it dips below 50%, you have to keep a close eye on the power levels because it diminishes exponentially faster. I’ve left home with 10% battery and returned a few hours later to find myself locked out because the battery had completely died. I didn’t have my physical key to unlock at the time but fortunately I was able to charge it from the external port using a USB-C cord and battery bank to power it on long enough to unlock and get in. Another con is the live feed takes a few seconds to load. But overall, this is the most complete smart lock I’ve owned and I definitely think that for everything it offers it’s well-worth the purchase. I praise it for being stylish, reliable, and loaded with features you’d pay double for elsewhere. I’d give it a 4.5 star rating if I could.

Good lock but unable to use -- the 3rd party app it uses will not accept a long wifi password. App actually gives a message to change my wifi password to something shorter. Perhaps if this was my only device but i have roughly 100 smart devices, laptops, tablets and electronics connected. Changing my password for a useless 3rd party app makes zero sense given the time and effort that would entail. A separate TCL palm vein reader deadbolt lock on another door actually uses a different app and connects. And no, that other app does nor recognizes this lock for install! I foolishly assumed this lock would use the same app. Ridiculous.

EDIT: I'm back here to say that I could not be happier with the customer service TCL provides. I had purchased my first unit and after a little while the Palm Reader stopped working. I had received an email from their support team and they proactively sent me a replacement to my surprise. It's rare nowadays that companies truly stand by their products and their reputation and I could not be more impressed. I purchased this new Smart Lock for our new home and it's incredible. I have 2 teenagers that kept losing their keys and this has made a huge different. Having the palm vein detector was the big differentiator against their competitors. I can be carrying groceries or other things and with a simple hand motion the door unlocks. We also have a house cleaner and just give her a code that's unique and no more issues. This thing has a lot of cool functions too that you can utilize. The battery lasts for a long time and pulling out the battery to charge is super easy. I have a portable charger that I use and never once had to remove the battery from the door lock making it more convenient. Great device for a very affordable price! you can't go wrong
