The Jul smart mug wants to be the Goldilocks of coffee cups: not to hot and not too cold.
The mug will let you control your preferred drinking temperature, keeping your coffee, tea, or other hot beverage at the ideal temp "from the first sip to the last drop." By spinning the base of the mug, you can make your drink warmer or colder and an indicator light will tell you when the drink is ready for you. Jul comes with a coaster that also serves as a wireless charger.
Jul says a pledge of $49 or more to its Kickstarter campaign will get you a mug and coaster. The company has already raised more than $158,000, well above its $50,000 goal. Check out the company's Kickstarter page here, but as always, pledge at your own risk.
