My minor complaint is that this is too small; typically university-style decals are meant to cover a lengthy portion of the window for optimal viewing.
My real dissatisfaction is that this decal is meant to adhere to the inside of the car window, which, if your windows are tinted (as most rear ones are) means no one is going to see this except for you.
When you combine the size and the way it's meant to adhere, you have a decal that you can't put anywhere should you decide the size isn't right, because anything else you stick it to will be displaying it backward.
I'd have preferred to pay more for something weather-resistant that can be stuck to the outside of my vehicle, so, off to Etsy I go!
