Defending yourself against the aggressive seat recliner

Sick of the person in front of you not being considerate when they decide to push that recline button?  Try this simple, easy to use gadget called the Knee Defender™.

Just subtly slide these small plastic devices onto your tray table frame and you are on your way to effectively adjusting the amount of decline allowed of the seatback in front of you.  They fit most commercial airline seats, and even come with a courtesy card, giving you the opportunity to fully explain to the offender in front of you what you are doing and asking for their understanding while using them.
