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.

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.

Solid device, Good support
Summary: 4 stars only because it’s been a short time though I would give 5 stars for support. I received the ULTRALOQ Smart Lock U-Bolt WiFi and encountered some random performance issues. In the end, ubolt support was able to help resolve the problems and I now seem to have a reliable smart deadbolt solution (at least for the last few weeks, time will tell). Details: The lock seems well built and the instructions are clear. The installation was straightforward. It is imperative that one ensures the deadbolt moves freely without resistance so the motor doesn’t jam. After install of the initial purchase here’s what happened: - >30% of the time the Ubolt App did not successfully lock or unlock the deadbolt - Most of the time it took multiple keypad entry tries from outside to unlock the door. Sometimes we had to eventually enter through another door. - could not connect via WiFi, and though it will use Bluetooth when no WiFi available, I still encountered the erratic issues above. For the WiFi issue, I determined that although my phone was sensitive enough and could successfully connect to my router (other side of my house) when standing near the lock, the lock could not. I used an online tool and my phone to measure signal strength at the bolt location and sure enough the signal strength was below the spec given by ubolt. The solution here will be to get a WiFi booster or Mesh router. In the meantime it will be Bluetooth only and I won’t be able to lock/unlock remotely. For the other issues, I contacted ubolt support and Savi really helped me out. After he sent me a number of troubleshooting steps he determined a replacement was in order. I received the replacement in a week or two, basically using the original deadbolt in manual mode (note that a hard key is provided) until the replacement arrived. I installed the new lock and so far I’ve had virtually 100% first try successful lock and unlock with either the app (Bluetooth) or keypad. I commend the support from Savi. When he did not hear any status from me after a couple of days he would check in with me via email. Very proactive. This was my first experience with a smart lock so I can’t compare with another company’s solution but at this point I recommend Ubolt if for no other reason than help is available when things don’t go as expected.

Works well after customer service helped to get it connected
I got the lock with wifi and without the fingerprint reader. Just the key pad. The lock looks elegant and feels very solid. The installation is easy and works well. Of note is that the lock's deadbolt needs to be able to slide freely without much resistance into the jamb portion of the frame. While the lock was able to get it locked, it always used three consecutive locking actions to get it in as far as possible. This is a great feature, but also told me it would work better if there's less resistance. So filed away a little bit of the striker plate in the frame and now the lock closes with a single action. Initially my lock would only connect to bluetooth on my phone, but not to my wifi, even though the signal was strong. I tried a few times to get it connected as instructed in the manual, but to no avail. I then contacted Ultraloq's customer service and they were very responsive and updated the lock's firmware. Now it connects well and works perfectly as intended. I have it connected to my Alexa and every night have a routine to automatically lock the deadbolt. So now I don't have to worry about if the lock is closed when I go to bed. So far I am very pleased with the lock and the service.

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.

little more than a toy for fun, do not use for remote access or secure control of your doors
So far, 5 days in I would say the Ultraloq is a complete failure. I purchased this for the primary front door lock at a home which we are not in attendance for months at a time but require temporary access for workers and guests. For this it is a complete and utter fail. What I have learned - 1) the unit does not have any reliable wi-fi. My $10 remote outlet switches are more reliable. The unit was installed in the front door with line of sight access to a 4 month old Orbi Mesh access point, which supports both 2.4 and 5Ghz. The AP is located about 15 feet from the front door with no obstructions. The unit requires wifi for most all functions on the app, unless your within short bluetooth range. In three weeks the unit has not remained connected to the wifi network more than 3 days. There is no particular reason it disconnects, I have a highly automated home and every other device, phone, computer, wifi lights, wifi plugs, wifi cameras, wifi ring doorbell, wifi ring remote ringer, wifi clocks, wifi interior door locks, etc. all have remained connected. The only single failed device is the Ultraloq/app. 2) When the lock disconnects it does not have the capability to reconnect, regardless of the reason for disconnect. This means that if for any reason including just random disconnect occurs on the lock it will not reconnect. The ONLY way to reconnect is to complete multiple phone reboots, remove the wifi connection from the app, connect to the lock ONLY via bluetooth, then reinstall the wifi connection. Each time it disconnects this is the process. I discussed this at length with Ultraloq tech support, this is the required procedure. This means you cannot operate these units remotely. So unless you plan to be at your home, everyday, and within bluetooth range, everyday, these units are not going to function. 3) The issue is software/firmware and is the same for all locks Ultraloq sells. The Ultraloq personnel will attempt to push it off on your wifi. They will tell you that mesh systems are not reliable (despite the actual fact that wifi mesh systems are more reliable offer greater resiliency and greater coverage areas), or that the locks require 2.4Ghz only (Most mesh systems offer both 2.4 and 5ghz and self select the one the device can use). 4) Ultraloq denies this issue exists but it is detailed by multiple users in the their own community tech pages. 5) Even with the "smart" open and autolock feature the system can and does fail. If only close the door partially the lock will make a couple of attempts to lock, once it can't the lock entirely fails but does not show the failure in the app. The lock will have to be manually opened, then the door closed for it to reengage. If you open the door or close the door without the manual opening of the lock the unit will not autolock. 6) logs are unreliable. Further attempting to access them can take minutes for each screen listing of logs. For me the app tends to timeout multiple times before presenting the data. I have found no way to download or access logs other than the log screen. 7) once the unit connects to a phone via bluetooth it will not connect via wifi, so you have to turn off your bluetooth, reboot the app, in order to get the app to access the lock via wifi. Despite all the features and the great reviews, these locks are not for reliable, secure use of a primary lock in a home or other structure.

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!
