Review on ZXUY Water Hydration Bladder Tube Cleaning Kit With 1X Tube Cleaner Brushes For Efficient Cleaning by Drew Springer

The shipping took a while, but not longer than was estimated. While I was waiting for this one to show up, I found one on clearance at Walmart and bought it. That one has a bunch of different pieces, which came apart and stuck inside the bladder. It was pretty much useless. This one is all one piece and collapses to fit through the mouth, expanding once it is inside. It fit fine inside my 2L Nathan and generic Bass Pro 2L bladder. There is some room to spare, but it keeps the bladder open so it doesn't mildew.
