Disappointed they don't stick better

These look great, but they fall off easily -- even if you make sure the window is clean and rub the front of the sticker to build up static. I wanted a clear sticker originally, but called and found out this company doesn't print on transparent material.So I just hoped it would work out. The main problem is that the back of the sticker is stickier than the front, but to use the sticky side on a car window it has to be on the outside of the car. If the clings were clear, I could reverse the image and could put the sticker inside my car window. With nothing showing through, all I can put on the window is the printed side -- and it barely sticks. I rated my other order of clings higher, but I am getting more frustrated as more people tell me they don't stick well. I will not order clings again and am kind of regretting these.
