So far so good

Have had it for close to a month now, the previous version of the app didn’t seem as reliable but they upgraded to a more solid-feeling app. Also on initial setup and installation I had to take out the batteries to reset the lock since it wasn’t integrating with the previous version of the app. Taking out the batteries that one time during installation fixed the issue and it has worked smoothly ever since. Pretty happy with it overall. I’d recommend a locksmith though if you’re not proficient with tools because I’m fairly proficient with tools but still haven’t been able to perfectly align the deadbolt with the doorjamb.

Does what is says it does

Installation was quite straightforward, using the lock is easy and love the autolock. The feature where the lock unlock as you approach the door does not work well, as it takes too much time for the lock to unlock. I turned that feature off.

So Far So Good

Installed easily enough... setup and programming of tenants was simple and intuitive... So far, U-Bolt Pros perform FAR better than the 3 UL3 Gen 2's that I also have that have various bugs, quirks, and have failed numerous times within 1 year of installation.... But only time will tell as it's only been a few weeks since install.

A good, high-tech lock

I've long used Schlage gear but switched to Ultraloq because of the problems pairing Schlage gear with WiFi, especially mesh systems that use both 2.4 and 5gB bands. Schlage customer support is useless. On the other hand, Ultraloq paired easily. I find it a bit confusing to use some features on the U-tech app, repeatedly forcing me to reload the app during set-up. And I'd like a bit more sturdy feel to the device v the current plastics. But the lock is, on the whole, extremely good.
