Query: Not that great

I purchased this item for my son, as I do not have tinted windows and he graduated from an infant carrier to a regular carseat. I bought 3 of them (one to use on the back window, and 2 for the side windows) and I must say they don't work that well. Sun still manages to hit my son's face, making the car ride uncomfortable for him. Not only that, the suction cups on the sunshades don't stick very well. I'm constantly having to stick them back up every few minutes. Would I buy these again? Definitely not, and I wouldn't recommend them either. Keep looking.
