(This review was collected as part of a promotion.) Absolutely AMAZING. The lock connected easily to my phone, and I can easily control it and see the settings from there. Very smooth and flawless app controls. Firstly, the features are endless! The best feature is being able to generate a unique access code and give it to anyone. You can set expiry or repeats on certain dates on these codes as well! There is an auto lock door after a set amount of seconds or minutes, and you can also see if the door is locked or not. Getting notifications whenever the door is unlocked/locked provides peace of mind. The touch screen is responsive and also has a security measure to prevent accidental touches. The installation was super easy. Removing my old lock and installing this took about 30 mins total. The instructions were super clear. Inside the box were separate boxes that were labeled and each corresponded to the instruction step. Probably a total of 10 screws used. Very easy to install.
