You'll never buy another brand of mattress protector after you use this one!  It's quiet (no sleeping on plastic bags).  It's actually waterproof.  It stands up to multiple washings (on cold, no bleach).  It withstood 2 potty training kids and remains stainless and functional to this day!  We bought 2 for each bed in our home so we would never be without one again.  Our mattresses still look and smell brand new as well!
