I can't tell how it felt when I saw the video of this product.I was pretty impressed by the idea of this.If this product works like the way it was shown in the video.Then I have to say that it is a life saving product.

We are building high rising building but not thinking about any measures to evacuate those in case of when any emergency situation arise.For example,think about earthquake or fire accidents.In this kind of incidents,it may save some people's life who won't be able to escape using the stairway or elevator.

Thanks for sharing the information of this brilliant invention.I hope we get to see more product like this in our life.
