I put this window cling on the driver's side passenger window. (It's reversible so it doesn't just have to be used on your car!) I had no issues with it bubbling or losing it's grip throughout the hot Nebraska summer or the Arctic blasts we had in the winter. Every time I get in my car, it makes me smile. Since COVID-19 began, I've been doing most of my shopping via curbside pickup. The curbside workers see it and it seems to just make their day. It makes me happy to bring a smile to those who have been working so hard during this pandemic!
