Query: Works well

The suction cups stay well on the window. I like the fact that I can adjust the size, and it doesn't have all the cutesy pictures. The only problem I had is I forgot I had it on at first, and I opened the car window. The suction cups busted off and got lost inside the door forever. Next time I'd try one that doesn't need suction cups, or supplies extra ones!
