I just got one and installed it two days ago. Really pleased so far. I went with the indoor cam but there's a wall mounted one and a doorbell one too. The app is really easy to use and I imagine super easy to manage multiple cameras if you were to have more than one.
Some people seem to be ignoring the word 'Ring' in the title of this thread which (as it's a brand name) I assume means that Thisoldbird is looking for a 'smart' (video) doorbell.
If you scroll down to 'Having trouble deciding?' here, you can click through the options to find the best model for your needs, Thisoldbird:
