A good smart lock
Works well! The app has decent features and customization. The proximity unlock works 95% of the time. The proximity lock for some reason is a bit finicky but their customer support is very good.

OMGOSH I LOVE IT
It's an easy install, took my husband about 15 minutes, set up is really easy, adding people very easy and there's 3 options, Admin, Standard, Temporary. You can set it up to notify you of every open lock or close lock, you can also elect who you always want to be notified when the a particular individual opens with code or manually opens or locks. I got the black one, I wish I'd gotten the white one, but no matter, this item is awesome, easy on the wallet and very nice looking. You can also link the app to Google Home and tell it to open or close the deadbolt. You pick the 4 digit code used by others on the account, can delete other users or set a time limit access by minutes, hours or days temporary guests have access to enter. I have an individual coming for 9 days to feed the dog, all I had to do was go to the app and pick the dates on the calendar. I got the set that comes with the bridge, and I can open it from anywhere. I linked it with Google Home, and like an idiot didn't get the finger print. But you don't need it, when my phone gets near the locked door, it unlocks automatically.

So far, so good!
My Yale/Nest lock became increasingly flakey, going offline sporadically until, after resetting it many times, it eventually refused to connect at all. (I worked the problem for a *long* time before giving up and buying this as a replacement. There were a lot of people online with the same problem and the "fixes" didn't help.) I was pleasantly surprised that the installation was easy. The only part of the installation that was poorly documented was the bit about the door sensor. The door sensor monitors whether the door is physically shut or not (since the deadbolt can be operated regardless of whether the door is open or closed). I watched the YouTube video and it explained things better that the written instructions, so, overall, installation was problem-free. The app is a little over-engineered, in my opinion. You set up "Addresses", "Locations" within an Address, and "Devices" within a location. I suppose it makes sense if, for example, you owned several properties with multiple buildings on each, with every unit in every building having two or more devices. For a person like me, with just one lock at a vacation home, it's overkill and unnecessarily complicated. The features of the app are great, comparable to what I had with the Yale/Nest lock. The two major differences are 1) that the ULTRALOQ has a sensor for when the door is open or shut and 2) the way to handle dead batteries. The Yale/Nest lock has contacts on the outside where you hold up a 9-volt battery to the lock, powering it long enough to get it unlocked. The ULTRALOQ has physical keys. I like having the physical keys very much, but they are no use if the physical key is not present. For example, if I wanted to give access to guests and the batteries were dead, I would have to drive hours to meet with them and get the door unlocked. It would be ideal to have both features: battery terminals AND physical keys. But I can't really knock it for not having a feature that I already knew it lacked. That said, the ULTRALOQ app tells me how strong the batteries are, which the Yale/Nest lock does not do. Another cool feature of the ULTRALOQ is that I can take it off the WiFi (and lose remote control capability) to extend battery life. I don't want to do that, but it's cool that it's possible. Replacing the batteries is easier with the ULTRALOQ. You need a tool or thin toothpick to get the battery cover off the Yale/Nest lock. The ULTRALOQ cover comes off just by applying gentle pressure. The ULTRALOQ has an "autolock" feature which seems a little too aggressive. I turned this off because I sometimes want to leave the front door open without the lock taking it upon itself to lock within seconds. There is also a feature to automatically unlock whenever a configured Bluetooth device approaches. That's also too automatic for me, but some users might appreciate it. Updating the firmware on the ULTRALOQ was a big pain. It took several attempts which failed randomly, despite the WiFi being strong and my phone being right next to the lock. That did not bode well, as it reminded me of trouble I've had with other devices. But it eventually worked. I would change my rating from four to five stars if the firmware updates worked more reliably and if the app was organized more intuitively. But, so far, the lock is working well and it has almost all the features I want.

So far so good
So far so good. Easy install and will tell you current status whether using the app or not. Many other smart lock devices only tell you the status if you use the app to operate.

Great locks with a great app
Works great. I have three of them and I’m now looking to add a few more. The app that they have works great and shows the locks as groups is this nice to open the app to see which locks are unlocked which locks are locked. You can also set it to lock as soon as you shut the door.

Nice, but WiFi access seems to be tricky and the magnetic sensor has trouble with reinforced doors.
Not directly compatible with 5GHz WiFi, but there is a work-around. I bought the lock because of its security rating and various features. The problem is if you have a really secure door with metal reinforced door jamb, the magnetic sensor will not work reliably, and without a sensor, there is no auto-lock feature. This could be easily fixed with a lock timer, but the manufacturer has not offered a solution. The worst issue with this lock is that a few weeks ago, the bolt motor started vibrating in the locked position. This serious malfunction could only be stopped by forcing the bolt to the unlocked position. What, if this had happened while we were away, with no means to unlock the door? And, recently, while I was on vacation, my wife found the lock in the unlocked position at night. She immediately disabled the lock by removing the batteries and relied on the mechanical key for a few days. I cannot keep using this lock, and I am looking to get a lock from a decent manufacturer. UltraloQ has completely lost my trust. The manufacturer sent me a replacement, but I am afraid to install it, given the negative experience I had with the first lock.

Good, responsive customer service.
Had this unit for about 2 years before the keypad started malfunctioning. Reached out to customer service and they sent me a new exterior assembly even though I was technically out of warranty. Much appreciated! The unit now works again as it did when I purchased it.

Simple & secure smart lock
Installed three of these locks, on front and back door and an outbuilding. Didn't need the most advanced features, just wanted an easy to use smart lock to do away with keys. They were easy to install and set up - and it's easy to create temporary codes for special purposes, such as access for a worker. The locks have worked without problem for a year, but recently one lock started beeping. I called the customer service number and was immediately connected to a real person - so nice to avoid those pesky phone tree menus. Mr. Real Person (Omar), patiently talked me through troubleshooting steps. When those failed, he initiated sending me a replacement of the lock. This is the kind of quick and effective customer service that stands out. I hadn't heard of this company before I instlled the locks, but I now highly recommend them. If, like me, you want a simple smart lock without advanced features like fingerprint and Apple watch recognition, here's your answer. Lock and unlock doors automatically, or right from your phone wherever you are. Simple and secure, backed by great customer service.

Good lock with good customer support
I’ve had this lock for a year and suddenly the lock button from outside stopped working. I was very frustrated as it was only a year old. I raised a ticket in the app, to my surprise, in 30 minutes I already got a call from their support line with suggestions how to fix it. It turned out that the wire inside the lock got disconnected, within 7 minutes I already had all fixed.

Good quality product
Worked well but needs a wifi bridge which can be a hassle but it was ok for us.

The door sensor is critical, and this version has it.
Great little lock to replace my ubolt pro with fingerprint reader. The major advantage here is the door sensor. This means that it only relocks when the door is closed. The other lock (without sensor) was destroyed by being slammed shut after relocking automatically ; when the lock was already out and this shook the internal mechanism loose. The other still lasted 5 years despite this. The app is fine if basic.

Muy bueno
Después de dos meses de uso diario, estoy satisfecho con su funcionamiento. La instalación es muy fácil y está totalmente guiada por el instructivo y videos de instalación. Si por alguna razón, alguna pieza del kit no se puede instalar en tu puerta, puedes usar la pieza que ya tienes en tu cerrojo actual y va a funcionar. Importante señalar, que la primera vez que se usa no abrió de manera total de forma automática, se atascaba. Se soluciona usando un poco de WD40 y listo. A veces tarda unos segundos en conectarse al celular y abrir con la aplicación, pero no es nada que sea más incómodo que llevar llave física a todos lados. Muy bueno en general.

Works Great!
It connects through wifi and we can program temporary PINs. We can also unlock the door remotely! Good product!
