Serves Purpose.
Color: 1a Peva Clear Premium, Size: 72"W x 72"L (Pack of 1)
Ok perfect! Although it could be thicker and the holes placement lower to match the curtin holes. I had to adjust the shower bar by lowering so magnets attach. And they may carry a thicker curtain I didn't check.

Thicker liner that stays in place and keeps water inside the tub
Color: 1a Peva Clear Premium, Size: 72"W x 72"L (Pack of 1), Color: 1a Peva Clear Premium, Size: 72"W x 72"L (Pack of 1)
I replaced my old shower liner with this BigFoot clear liner, and it’s a noticeable upgrade. The material feels thicker than the typical cheap liners, which helps it hang properly instead of sticking to you while showering. The weighted bottom is one of the best features. It keeps the liner in place so water doesn’t leak out onto the floor, even with a strong shower stream. Once it’s set up, it just stays put without constantly needing adjustment. Installation was straightforward with standard hooks, and the reinforced grommets feel durable enough that they won’t tear easily over time. The clear design is also a plus because it keeps the bathroom looking brighter and less closed in. It wipes down easily and so far hasn’t shown signs of mildew, which is important for something that’s constantly exposed to moisture. Pros: • Thicker material than standard liners • Weighted bottom keeps it in place • Reinforced grommets add durability • Clear design keeps bathroom bright Cons: • Slight plastic smell at first (fades quickly) • Still needs occasional cleaning to prevent buildup Overall, this is a simple but well-made shower liner that does exactly what it’s supposed to do. Great upgrade from thinner, cheaper options.

Thick and clear
Color: 1a Peva Clear Premium, Size: 72"W x 72"L (Pack of 1)
I like that this shower liner is clear, so you can still see the main shower curtain behind it. The magnets at the bottom help give it weight and keep it against the tub, so it doesn't blow around. The material also feels thicker than cheaper liners. So far, it’s been working well.

The material is thin, and see thru. Haven't had any problems with it so far, and I've used it for over a month now. No soap scum, no build up of any kind. A really Great product! The material is staying really clean looking.
