Query: Shade does not stay on window... Useless!

Fortunately, we purchased this product at walmart so we won't have a problem returning it. These munchkin shades look well made, but will not stay on the window for even a short 20 min car ride. The bottom suctions don't work at all so the shade flops around and my 17 month old can reach the bottom and play with it. What a piece of junk. Had the manufacturer used a higher quality suction cup, this product would be excellent.
