efore making the final design prototype, I decided to take
the holder with me on my morning trip to the school. Usually, I am carrying a heavy bag in one hand and using my smartphone in another. Almost ideal situation to check. Here are some notes about the experience: •
As expected, one hand is still free, and I can take selfies.
•
While carrying, the holder is shaking a bit. Thus, it was correct to pic dimensions close to the cup. Probably, the smaller container will be not so secure in the holder, but folded accordinon can help it.
•
It became clear that the ring must be easily and freely up and down on the surface. Especially it is seen when you up the hand to hold something, for example.
•
Bag legs are definitely useless and must be replaced with flat silicon rings.
