Whenever you are buying a product through Amazon it would be better if you have a glance on the previous reviews.
There are reviews on almost every product
Since it became an open site to sell things, many dealers are miss using it they are placing bad products! Some products are not original branded, some are dameged, some are misplaced.
Though there is a option of reversing the product., It is not satisfying the customers it is just waste of time
I regret what happened to me. So recheck the dealer and the product while shopping through online stores.
