Bests & Worsts Reviews from Amazon

So got my doorbell and had it hardwired...good to go right? Well, a few months later the motion sensor and the live view stopped working. So I called Tech Support and found out that even with hard-wiring, the battery will run out of gas and need to be recharged. This requires removing the unit and jacking in the battery with a USB cord. Nowhere on the APP is there a indicator that shows that the battery is getting low! So we could be traveling in vacation and all of a sudden without any warning the ring doesn't work!! Imagine that? Checked the box and couldn't find any mention of this important safety non-feature of the doorbell. I like the product but am extremely disappointed in the fact that it can stop working at anytime without pre-warning.
