I have one of these along with two of their UL1 door handles and they are very nice devices. I’ve had them for over 2 years now with no issues. They are very well built devices and high quality.
I will say though that if you don’t have an outlet really close to the door you are going to put this on the wifi dongle was always it’s weakest link. The main product itself is legit. The wifi dongle you have to waste a wall outlet for has the weakest Bluetooth range I have seen. They have been quite temperamental with my UL1s as well but I don’t really need the remote use ever so I just stopped using them.
They have a new model now that combines the deadbolt and wifi dongle into one unit with some additional improvements. Idk if you would think the newer model is worth the money but I would seriously consider it if you would end up wanting a solid remote experience along with not having to waste wall outlets.
