Great lock, almost perfect!
We have owned this lock for 1 year. (I wrote this review at 2 months, but we still love the lock, and even bought the cheaper code only version for the back door, since we could share the wifi bridge with multiple locks.) Ok, first of all, installation was a breeze. We were replacing a manual deadbolt, and I'm not even sure we looked at the directions - everything went together without a hitch! Setup was pretty easy too, though if you set it up from the lock itself, and then you want to use the app, you'll have to reset the lock and start over. But even with setting up, resetting and doing it again from the app, we were up and running in about 30 minutes. The lock detects my and my wife's fingerprints just fine. My mom, who is 92, not so much. We assumed her complaints about not being able to grip with her finger tips any more was a grip strength issue, not a friction issue, but maybe not - this lock just does not recognize her fingerprints. It allows her to save them, but when she goes to open the door, it rejects her every time. But as she doesn't go out on her own any more, and her code works fine, so it's not a big deal. The fingerprint is more so we can get in quickly if there is an issue, without having to have her key in hand, so it is fine for us. The app is good, and simple to use. Sometimes it doesn't connect on the first try, but it's like it times out too early, as the second try is always successful. There are indicators in the app as to what method it is using to connect, which is good to see what it's trying to do. It's very simple to add a user to the lock, and I like that you can choose for each user if they have a code, a fingerprint, or the app, or any combination. Each user is allowed two fingerprints. (I saw another user saying "only two?" but for me, based on height and doorjamb, I really ever only use my thumbs to open the lock, and 95% my left thumb. It's too awkward otherwise.) You can also disable a user without deleting that user. We have a code that is shared with the neighbors if we go out of town, but when we are in town, we disable that user. A user can also have scheduled times or days when it works; for example, you could allow a health worker access between 9 and 12 every weekday, but nothing else outside of those hours and days. You can set up a temporary code for say a repair person, that expires after one use. I've never seen quite so many options on a lock! The only "connected" service I've tried this with is IFTTT, and I'm disappointed in that. I have motion sensors set up in the house to "see" if my Mom is moving around (in a non-invasive way) and the triggers feed a spreadsheet. I'd like the lock to do the same thing, and IFTTT is set up correctly to do so as it works occasionally. Maybe 1 in 10, but that's generous. I know that it *should* work, because the text notification I get seems to work 100% of the time. So I don't really have a theory as to why the other fails - both are internet based - if one works the other should. To respond to a few other reviews I saw: It's never given me a "lock jammed" warning. It's never lost its memory on "handing" - whether the lock is installed left side or right side. I don't use the "automatic unlock" feature. We purchased this lock to give us anytime access to the house without having to find the key, and to allow outside access to the house if necessary - she wears a medical alert device, and now the responders can get in if needed. So everything else is fluff, and we are very happy with this lock!

Wonderful smart deadbolt, but configuration can be difficult
The U-Bolt Pro fit perfectly in my door to replace my older "dumb" deadbolt. No hassles there-- easy to adjust for diameter of door hole and distance of the hole from the edge of door. Was able to use the previous lock's strike plate in the door frame. The outside part of the lock (with the keypad and fingerprint sensor) has some wires with a rectangular plug that fits into the inside half of the lock mechanism. There was nothing in the instructions on how to properly orient the plug, which could apparently go in both ways. However, on installation, I could open and close the lock with the phone app and by twisting the inside knob (like on any deadbolt), but the outside keypad and fingerprint reader didn't function. The phone app also did not offer the option of programming the fingerprint sensor. There was no mention of this problem in the installation guide, so I had to search online for advice (no support available on weekends). It appeared that there might be a problem with the electronic connection between halves of the lock. I took the two halves apart and re-seated the wires with the plug oriented in the opposite direction. Then, the keypad worked, but I still couldn't program the fingerprint reader. Again, no advice in the limited printed directions. Very frustrating. I decided to wipe the memory of the lock (again, found out how to do this online), reset it to factory configuration with the pin provided, deleted my phone app and reloaded it, and then re-programmed the lock from the beginning. This time , it asked to register the fingerprint of all users as they were added (which it didn't do before) and it finally works fine. I was able to plug in the included WiFi bridge in a nearby outlet and connected it to my WiFi. This was a bit of a hassle because it cannot connect to a 5G network. Fortunately, my router also has a 2.4 GHz network, which worked. Now I can control the lock from anywhere I have a WiFi connection. The keypad and fingerprint reader work perfectly. Aside from the installation hassles (caused by a poor initial electronic connection between the two parts of the lock-- I blame myself mostly), the lack of 5G internet support, the total absence of problem-solving instructions, and lack of weekend support, I think this actually is a great product. I am very happy with it. Just be careful to assure that the electronic connection between the outside and inside lock parts is properly made before trying to program the lock!!! Be sure to use a less than 5G WiFi network. INstall on a weekday. Then you're all set.

Set-up is time consuming
Physical installation of this lock went well. Configuration of the lock was difficult and took me HOURS. Documentation was limited and inaccurate, setting up NFC entry with both Android and iPhone was unintuitive. Updating firmware took long and failed multiple times. Lock only supports 2.4Ghz wifi which was a bit of a pain with mesh network. Honestly, the lock works fine now that it is set up but I didn't think it would take almost a whole day get it completely installed. If you are not technical and willing to experiment, or are using it in a very simple way (all Android devices or all iPhone) then you might want to consider other options. Customer service was very attentive so: 3 stars due to lock set-up trouble and plus 1 for solid customer support.

I like that the number pad is tactile, one of the few if not only digital lock i found usable by the number pad for a blind person. The keys are made of rubber, and has a springy feel to it. It is around the fingerprint sensor in a circle, somewhat like an old-fashioned telephone pad Thumbprint sensor is sensitive and I as specially found the automatic unlock function when I am nearing very handy when my hands are full. Only complaint is I have to go far enough from the property for it to recognise that I am coming back and automatically unlocking. Overall a fantastic product at a very affordable price point that is accessible and easy to use.

Muito boa mas não consegui sincronizar de outro bairro por exemplo (era o que eu mais queria para poder controlar o acesso de longe). Para usar a fechadura pelo celular tem que estar ao lado da porta (não faz sentido pra mim).

Funciona muy bien. Lo mejor es que funciona con las huellas dactilares ya que es algo muy muy practico. La apertura automatica por bluetooth (por cercania) no siempre me funciona como me gustaria, pero la verdad es que tampoco es algo tan critico si funcionan las huellas. Agregar personas es muy sencillo tambien. Super recomendable.

My first smart deadbolt. I replaced a normal key only deadbolt to put this in and I have to preface by saying as I often do on reviews which involve a screwdriver :P that I am not into DIY and feel like I'm hopeless at it. That said, this was an absolute piece of cake. If you have an existing standard deadbolt then this install is single digit minutes if you know what you're doing. I was taking my time - even reading the instructions which are excellent - because I was so nervous about it and even there it took me about 15 minutes to do. Most of that being double checking to see what I'd missed because it seemed *too* easy. But it was done. So what is it like when installed? Well I actually do love that it comes with the door sensor so you can - if you want, and only via the Ultraloq (Xthings Home) app make it so that as soon as the door is closed it locks. Alas this sensor / capability isn't exposed to HomeKit so it's via the app or not at all. (Well of course you could add your own HomeKit or Matter sensors to the door and use HomeKit automation if you wanted... but that's off topic for this unit) I love that it has so much variety of options for locking and unlocking. You can have the door auto lock when closed, or you can have it that if you press the Ultraloq button on the lock outside it will lock or you could even use a key if you wanted. To unlock you have HomeKey so tapping your phone to the outside unit (and can choose to make it work without unlocking the phone or requiring your FaceID unlocking before it will work), you can put in a pin code (4 - 8 digits) and can obfuscate that with "anti-peek" mode by putting random stuff before and/or after it before trying to unlock to prevent anyone grabbing the code if they're watching. You can use the NFC cards supplied with it, and you can use the key which is a great fall back to have should it say run out of juice. You can also set up temporary pins which I've tried out for a future case where I will have pet sitters coming around. Perfect. Honestly, I was a bit suspicious of this but at the price I thought it was worth giving it a go given it has so many features and integrates so well with Apple HomeKit. I've had this in place now for a week and I've been very happy with it so far.
