Manufacture called A llaunched a product called AB. Company gives review sample to reviewer, and review said bang for bucks product. Manufacture again launched another version of AB product revision 1.2. But that model with latest revision found with some problem. Then people who bought the latest model AB 1.2ver curses the reviewer that the product is Sh!t , reviewer is sh!t blah blah... But is the fault really of a reviewer because he reviewed the original MODEL AB not with revision 1.2. So blame the manufacturer not the reviewer.
Peace
