Review (1/5): DO NOT BUY!  YOU WONT BE ABLE TO REMOVE THIS FROM YOUR SHOWER TILES!!!
I purchased this and after about 3 months the anti-fog properties wore off. I struggled to use it for about 9 more months until I finally got fed up with this and stopped using it.
I attempted to take this off my shower wall today and it's been a complete disaster. This DOES NOT easily remove from your walls. It's all broken into small pieces on my wall and there is small bits of silicone stuck that I can't remove. I wish I never bought this product, I absolutely hate it.
