Look, a couple hundred bucks is a lot of money to spend on a doorbell. I get it. But the Ring Pro has absolutely been worth it. The Pro is the best of the best, and I haven't once regretted buying it.
If you don't want to drop that much cash, also check out the original Ring. It's a little bigger and the camera's not quite as advanced, but it's still an excellent product — I used it for many months.
And installation is remarkably simple. If you've ever swapped out a light socket or installed a ceiling fan, it's that simple. (Basically if I can do it, YOU can do it!!!) But if you do need help, they've got some kick-ass tutorials.
