When you go on a diet or restrict your diet, you check the calories of "food", but isn't "drink" a surprising pitfall? Many people say that they don't realize how many calories and sugars are contained in the juices and coffee drinks they drink casually.


Developed by MARK ONE, led by Justin Lee, the tumbler "Vessyl" allows you to analyze what ingredients are in the drink you pour in very accurately. US media WIRED reports .


Vessyl is a tumbler with magical special features. A sensor mounted on the inner wall of the cup instantly analyzes the calories, sugars, proteins, caffeine, and fat contained in the liquid inside.


Vessyl can analyze any drink on the market, including coffee, juice, beer and wine. According to the media, the analysis is "surprisingly accurate." It also works with iOS or Android apps to track ingredients that suit your purpose, such as "diet," "caffeine restriction," "muscle building," and "comfortable sleep."


Vessyl is also characterized by its stylish appearance while having all these functions. A beautiful body that fits comfortably on your dining table or office desk. This smart design is also packed with Lee's commitment.


Vessyl is currently accepting pre-orders for $ 99 (shipping not included). It will be priced at $ 199 when it goes on sale in 2015, so if you want it, order it now at a bargain.
