I had high hopes for this thing since our bath tub drain gets clogged with my and 7 yo daughters hair. I have to give 2 stars for genuinity but it's poorly executed to get more stars.
I plugged tub drain with this thing and went to shower without having to wash my hair. By the time I finished my shower tub was filled with water, making me have to remove this thing in order for water to drain and rince my legs. Holes are too small for normal water flow. I don't recommend trying this product and it certainly not worth the asking price.
