Well made
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
The magnets hold well. The grommets are sturdy. The plastic is a bit thick and doesn't like to lie flat against the tub so it is constantly brushing you while you shower.

Exactly what they say it is.
Size: 72"W x 72"L (Pack of 1), Color: 1b. Clear-heavy
Appears to work exactly as advertised, and quality is very satisfactory, which is always a pleasant surprise on Amazon. Magnets are strong enough, plastic feels pliable and durable. Don't forget the rings aren't included.

Perfect Weight

Is a perfect liner. It’s not super thick or heavy. Easy to hang.

Good shower liner
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
Actually works! No soap scum or mildew. I have had this shower curtain up since December and all I do is rinse it off. No soap scum. Good item. Good value.

Too lightweight and flimsy, but it does the job
Size: 72"W x 72"L (Pack of 1), Color: 1a. Clear
This shower liner works as expected, but it is a bit lightweight, and will drift around in the shower.
I will look at getting a more heavy duty one in the future. This one has the 3 magnets, and that isn't enough.
I would recommend getting one with double the magnets and a thicker plastic. I went cheap and regret it slightly, but at least these things are made to be disposable.
Other than that, the durability seems good, and it looks and feels like you would expect, but as stated, the plastic is flimsy and flutters around. Seems fairly mold resistant vs other liners I've used from the store (like cheaper Walmart ones etc).
