Amazon currently has the Ring Video Doorbell 2 on sale for $169. That is good for $30 off of its regular price, and also brings it down to its all-time lowest price.
The Ring Video Doorbell 2 is a great video doorbell to pick up and install in your home. It has a built-in video camera, so you can see who is at your door without actually going to your door. Additionally, you can record what's happening on your porch at all times, so you can see when FedEx delivers your package, or if someone is stealing packages off of your porch (a big issue during the holidays). The Ring Video Doorbell 2 does not work with Alexa yet, but the company is planning to add support in the near future. For now, you can stick to using the Android and iOS apps to check on your front door.
