It does what it promises. I wish I had discovered it from the beginning. Especially in my area where the water is not just hard but a cousin of The Rock, as soon as I finish my shower I use a squeegee to get rid of the water and I'm good to go!

When I read the description, I didn't believe it would do anything significant! I applied it as instructed, which is very important, and indeed the glass in the shower became new. In the first use, I saw a big difference as the water fell and drained straight away. Now we just have to see its durability over time. Anyway, this product has impressed me once again, which is important!
