Great lock for glass inset door

Very happy to find a digital lock option for our door with a frost glass insert The slim design worked perfectly. Malcolm was great to work with for installation Only thing that could be improved is the digital display is hard to see when the sun shines on it.

Amazing Lock and Company

I found this company online as I was searching for a smart lock for an old Pella door. Not only did they immediately respond to my email, but followed up the next day with a telephone call to make sure all my questions were answered. I couldn't be happier.

Great lock, needs a bit more app integration

Installed for greater than one year. Installed to a most difficult location and the only lock that would. I agree the access through the Tuya app is disappointing and lacks needed enhancements. Mine does not unlock via the app which is limiting. None of the ways the app is said to integrate works, ie. Temporary pass codes, unlock commands, etc do not work Installed for greater than one year. Installed to a most difficult location and the only lock that would. I agree...

Great castle with many possibilities

I bought this lock for my main entrance door to replace my aging TSE fingerprint lock system. Installation was a bit tricky, as the handle set is only designed for thinner doors, forcing you to buy a square steel bar from a hardware store and cut or adjust it to the correct length.

Good alternative

The installation was a bit more complicated than expected because the dimensions aren't standard, but the function is great.
