Despite how they look, these Rollkers electronic shoes aren't made for skating. Oh no, no, no. They're "under shoes" made for walking. Just strap them on, take some steps, and your average walking rate is supposed to increase to up to seven miles per hour. Thanks, but really — no thanks.

Let's call this what it is: a smart belt that tells you when you're gaining weight.

Yup, this Breo eye massager exists, and you can buy it now for $45 to $140. Just slip it on and feel air pressure, vibrations, and infrared heat come together to totally creep out soothe your eyes.

See this? It's called an O2CHAIR from Innovzen, and it's supposed to help you relax. A little device sits under your nose and emits oxygen — as you breathe, the chair moves up and down to help you breathe deeper. Preorder it now for $9,500 or, you know, spend that money on something more useful.
