I absolutely choose these waterproof polyester liners every time I need a new one. They last a long time and can be washed in your regular washer to keep them looking like new. They don't feel hard and cold they way cheap plastic does and are so easy to keep clean. Which keeps down the mold in showers that bothers those of us with allergies. Wonderful product!

Pros: Great price and durable material and quality. 
Cons: They could come in colors but that has never bothered me.
