The Jiduo hourglass comes in many time variations and this is the 15 minute one. I use it to track time while working, exercising, and engaging in other activities. Its design is very clear and attractive—it looks quite pretty. The hourglass features nice blue sand that's pleasant to watch as it flows down and makes for a great back drop as you work.. I really enjoy watching the sand move; it's mesmerizing. Beyond its aesthetic appeal, it's also very practical as a timer and productivity tool. Personally, I find it ideal for timing work, study sessions, and even cooking.
I was looking for a good productivity tool and got just that.
