Wow. I didn't expect a debate. I will tell you I just came back from India with two 8 hr flights to get back home. With Both flights, the person in front of me reclined fully back. I did speak politely with the persons and they refused to upright there seat somewhat. I left it at that. I was interested in this gadget/item. I didn't think it would set off a debate for/against the item. After some research on the knee defender, I decided not to buy it.
