This self-stirring mug is insulated to keep hot drinks warm and cold drinks cool.
On the outside, this thermos-style mug looks like the Canon 25-105 mm f/4 lens, which costs $1,000. In reality, it is a relatively inexpensive mug that is meant to hold hot or cold beverages -- which is clear when the top is twisted off to reveal a stainless steel, insulated interior. With two AAA batteries, the mug can stir one's beverage of choice by itself with the simple flick of a switch. The self-stirring mug's small shape makes it portable and convenient for commuters.
This mug's unique concept and affordable price tag make it the perfect gift for coffee drinkers with a love of photography.
