Query: Do not waste your money

I had an old sun shade that just wasn't what it used to be. So, I purchased this one after reading the reviews. I received it last night. I used it during my lunch time today. When returning to my car to drive back to work, I was very disappointed. My new sun shade had large bubbles in it in several places. Spend your money on some other sun shade. This one is not worth anything.
