Study Ball
The Study Ball gadget is a prison-style ball and chain that you can program to keep track of how much time you spend studying. Once you’ve selected the desired duration, you chain the ball to your ankle and the manacle won’t come off until the schedule study time is up.
A red LED indicator displays the “Study Time Left“ and keeps you informed as to how much longer you’ve got to keep studying. The ball and chain are made of highly durable steel and weighs a total of 9.5 kg / 20.95 pounds, which makes it difficult to move while wearing it.
Quite often, students who are having problems concentrating tend to get up every ten minutes to watch TV, talk on the phone, take something out of the fridge, and a long list of other distractions. Were they to dedicate all this wasted time to studying, they would optimize their performance and have more free time available. Study Ball helps you study more and more efficiently.
