Perfect Drink PRO Smart Scale: Become a mixologist with a little help from this smart scale, which features Bluetooth technology and a downloadable app that make it easy to pair with your phone or tablet. Just tell the scale what you have in your liquor cabinet, and it lets you know which drinks you can make. There's no need to measure ingredients, since the scale tells you when to stop pouring.
This is a fun product, and the latest version of the app is pretty solid. I especially like the "cabinet" feature that compares what you have on hand to what drinks you can make. An app upgrade opportunity that would really be slick is if the app would keep track of how much of your cabinet stock was used, then pre-populate your shopping list for you. Maybe in the next release. Overall, works as advertised, fun to use, and nice to have a virtual bartender!
