NutriBullets are great blenders if you can't shell out for something like a Vitamix, but their Bluetooth-enabled model might well make you scratch your head. Bluetooth? In a blender? What for? We actually had a lot of fun playing with this little guy, which uses a smart scale to help you weigh out smoothies and sauces with perfectly tracked macros. It's not, strictly speaking, a necessary object—you could accomplish the same thing with a cheap kitchen scale, a regular old blender, and Google—but it's also not useless. And if you have a loved one who's keeping a close eye on their nutrition in 2019, this blender provides a fun and easy way to do it (at least for foods you can slurp). $100.
