I firmly believe that I paid for nothing.<br />First of all, it is too heavy.<br />Second, it does not keep iPad tightly. When I put my iPad in different position, the case separate from iPad.<br />Third it is not convenient for iPad input/output. When I need to charge iPad, I have to force to plug the charge cable, or move the case. When I want to turn up/down the volume, I can not reach the button easily.<br />So I don't like it.[[ASIN:B004HD5EXO Technocel Leather Flip Book Case/Folio for Apple iPad (1st Generation) (Black)]]
Output:
Negative Review
