Review on Fogless Shaving Suction Cup Shatterproof Portable by Mark Clark

So I love this little mirror! However, I don't know if it stays fog-free for the entire time I wash my hair, which takes around 30 minutes. I saw someone walk away like a 3 paragraph review of a fight, he/she drained the water and took the mirror off the wall. I don't know if you read the instructions, but it's VERY easy. Because there is a part that you twist to tighten the suction and twist to loosen the suction to make it easier to take it off the wall. And when it's hanging on the wall you do NOT need to take it off to fill it with water because as you can see in my drawing the mirror rotates so just turn it and the water just falls into the tub/shower . And it comes with a small cup to fill up the mirror.
