Ring belongs to Amazon, which gives the retail giant complete freedom to price these video doorbells however aggressively it wants without worrying about profit margins on individual units. Amazon's strategy focuses on getting Ring devices installed in as many homes as possible and knows that subscription revenue and ecosystem lock-in will pay off long-term even if the hardware sells at cost or below.

We're on the cusp of Black Friday, and while TVs and laptop deals get all the glory, practical gadgets are already on sale too.

Smart home sensors have gotten pretty good at detecting when you walk into a room, but they're still terrible at knowing when you're actually there. Most motion sensors trigger when you move, then assume you've left the moment you sit down to read or work at a desk.

Most video doorbells are either a pain to install or stick out awkwardly on your front door. For renters, apartment dwellers, or anyone who wants security without drilling holes or hiring electricians, the search for a good-looking, easy-to-use doorbell can feel endless. Most options force you to choose between installation simplicity and actual performance. The Wyze Battery Video Doorbell addresses these frustrations with a minimalist design, flexible installation, and smart features that make porch protection as simple as it is stylish.

The PartyBox 720 measures 16.4 x 37.1 x 16 inches, compared to 15.7 x 35.6 x 17.2 inches for the smaller 710, and expands the two 8-inch subwoofers to 9 inches. Unlike the 710, the 720 can also run on battery power, so users don't need to hunt for an outlet. It comes with two of JBL's rechargeable 600 batteries, which provide up to 15 hours of playtime, according to the company's press release.
