After reading a number of product reviews on the Trayblecloth, I decided to give it a try with my daughter. I was dreading the 5 hour flight we were going on, and this little product just seemed to be the perfect thing. It's a tray cover for the tray table on the airplane that just slips right over the tray and covers the dirty surface. So no more worrying about those surface germs! Not only that, the Trayblecloth has a clear vinyl pocket where you can insert reusable games, so the tray can be used like a whiteboard, and even comes with the dry erase markers. My daughter loved it and was quiet and entertained for long spells (while I read my book!) This Trayblecloth also has very cute, small pockets along the front, where we stored a small deck of cards and the markers. There's a larger stretchy pocket under the tray to store a few larger things. I didn't have any trouble locking the tray with it on, either. The website is www.lovetotravelproducts.com, good price and free, educational, reusable games that you can download,too! I love this product!
