I've only lost one letter from the CrazyDriver ones I got, and that was probably my own fault. (and mine don't have Will'* ugly mug reflected behind them! Just mine). Other than that, no problems whatsover.
AND, I have the big banner on my rear window.
I did the "print on paper and tape to the window" thing. The only problem with that is the sun cooks the glue on the tape, causing it to come loose and leave a crusty film behind. I had one in each of the non-moving front windows. One fell off, one is peeling. Still easier than removing goo from the paint, tho
