Massaging Backpack

I think it's a nice business idea. Because it's a compelely new idea and don't have a lot of competitors. This product is for the people who travel a lot or use backpack a lot. While they find the U.S.P, at the same time the product has technology. So it's not very easy to copy.

But I think this product still has some weaknesses. First is how big the marked is? We do have some people need this product, but how many people like travelling and use backpack a lot? So I think the market is not very big. Another thing is, this product can't change the weight of the backpack,so do the people who carry backpack really feel comfortable? So there're still some problems we need to solve.
