Wish it was cheaper though

Have Huper Optik CS70 on my windshield for almost 5 years now. still effective on hot noontime. nice also during nightime driving. my only gripe is that it does not filter the glare of sunlight and that you need sunglasses while driving. CS50 is I think the "sweetest spot" between night and daytime driving. I havent tried the CS30 though during nighttime driving....
