I brought this product from a online shopping website. When I saw this product I feel it is not a good one, but then I just did a research and I found that it is american army certified, but I did not believe that.When I brought that product I also conduct toughness test and I found that it is really durable .To do so I through it from a height of 2 ft and I found that it works finely. When I try to separate its different parts I found it has a protective cover and a rectangular case which protect it from the impact of different kind of force.I suggest you that you should go for it. Thank you.
