They are scammers and take your money you get nothing in return but a sticker to put on your window. They never contact you after you install it. They got 45 dollars from me for free. Just a trash company. I advise not using this company. As they are all scammers did not even offer to refund me my money. Also their web site is unsecured and will steal your info. This is not a USA based company. Beware.
