The Halo Touchscreen WiFi enabled lock offers keyless access to your home. The process to install it is very basic and simple. I noticed the lock ring holding the knob on the inside of the lock was defective. I was fortunate enough to have plies to repair it; however, I was disappointed to see it was defective out of the box. I recommend d doing a very thorough inspection of your device prior to installation and be sure all parts are present and I. Working order prior to installation. Overall, this is a fair product.
