RoboStir

The RoboStir is one of a few similar products which claim to automatically stir pots on the stove. If you’re cooking gravy or sauce, you have to constantly stir the pot and scrape the bottom so it doesn’t burn. You have to scrape the entire surface area of the pot to keep it from burning in spots. So even if the RoboStir worked, it wouldn’t do a thorough job.

Of course, if you read the reviews, it doesn’t work at all, and falls apart within about a minute.
