Simply put, the recording quality is great, but it doesn't continue to record the entire time there is motion. For example, a truck pulled into my driveway and it recorded that for about 20 seconds, then it stopped. It did not record when the driver got out and walked around. It seems like it times out between recordings, so you definitely get gaps where there can be a great deal of activity.
If you want incomplete recordings, this is the device for you.
UPDATE 08/2020: I have increased my rating from 1 to 4. There are two reasons: 1) I decided to hardwire the camera. This was a game changer. It almost acts like a different device in it's ability to effectively record motion. In fact, I would NOT recommend this device if using on battery power, but hard-wired, it's super. The battery is nice in the event of power interruption. The Ring doorbell camera also works really well with the Ring Security System.
2) Since my poor review, Max from Amazon reviews reached out to me and we worked through some of my concerns. His service and knowledge have been amazing. I am very impressed with the proactivity of their customer satisfaction team.
