Bests & Worsts Reviews from Amazon

I got this product while ago, after the first time washing it... I had to throw it away. It's not washable, there is other one cheaper and you can wash them and work very good. The reason this product gets good reviews because the seller send you email right after you receive the it and ask for review, so most of people give it 5 stars cuz when it first comes it is good, but as I said before... Not useful after washing
