Ring Battery Doorbell 2K (newest model), Speckled Gray, ASIN B0FHJ7TKZM

Here's an easy one for anybody who's been meaning to put eyes on the front porch. Amazon has the newest Ring Battery Doorbell 2K in Speckled Gray at $39.99, down from a $99.99 list price, and it's shipped and sold by Amazon itself. As of Sunday morning it was in stock with free delivery. It runs on a built-in rechargeable battery, so you don't need existing doorbell wiring to put one up, and it sends 2K video and two-way talk straight to your phone. Two things to know before you buy: saving and replaying recorded video takes a Ring Protect subscription, sold separately, and the USB-C charging cable isn't in the box. Amazon marks this as a limited-time deal, and prices move, so confirm the total in your cart before you check out.
