Query: Not a Good Product.

The problems of ths product are:1) It doesn't fit in my windows. I'ved tried it in my 2 cars but still it doesn't fit in it.2) The weather strips are too short. I searched it on the internet for additional weather strips but it was not available. And for all I know is it is really not available in market/stores.3) The solar plates must be facing directly to sunlight. There are some instances that the AutoVent is not working because of the angle of sun rays.4) The strips are hardly to remove. If you set it up for the leftside of your car window, it should always be at the left side. if you choose to change the position to the right window, it is hard to remove the strips from the AutoVent to set it up for the right window.5) the AutoVent is not practical if you are installing it up if you are in a hurry.
