For all those night crashers and constant workers, the best gift you can get them is this heat sensing mug. Designed with a heat sensitive Wi-Fi sign, the mug starts filling up bar after bar when it is filled with a hot beverage. Once all the bars turn blue, the drink is ready to be consumed.
Whether it is your teenage children burning the midnight oil during exams, or your spouse looking to reenergize in the middle of the day at office, the Hotspot Heat Sensing Mug would be the perfect gift. The mug is available for $13 on Amazon.
