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.

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

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).

The ultimate water bottle
Color: Iced Breeze, Size: 24 Ounces
I can’t believe I’m so excited about a water bottle. The design is amazing - I love that there’s no straw poking up but there’s still a straw sip function. I like that the carrying hook doubles as a lid locking mechanism. This bottle feels very sturdy but it’s sleek and easy to grab - I have small hands and it isn’t a problem for me to drink from with one hand. It’s also really nice that this bottle fits in standard couple holders both at the gym in the machines and in my car. The color selection is so fun and I am pleased that my bottle looks exactly as pictured. My water has stayed cold and my ice cubes frozen for over 12 hours now. Cannot recommend enough!

Keeps drinks cold all day
Color: Very, Very Dark, Size: 24 Ounces
We got this Owala bottle for our son to use as his everyday school water bottle, and it has been excellent. The 24oz size holds plenty of water for the school day without being overly bulky or heavy to carry around. The insulation works extremely well. Drinks stay cold all day long, even when the bottle sits in a backpack for hours. That’s probably the feature we’ve been most impressed with so far. It’s also been great for car trips since it keeps water cold for extended periods without needing constant refills. The design is really well thought out too. The built-in straw makes it easy to drink from quickly during class or while traveling, and the lid feels secure and leak-resistant when closed. It also has a clean, modern look that feels a little more premium than many standard water bottles. Build quality feels solid overall, and it seems designed to hold up well to everyday use from school, sports, and travel. Overall, this has been a fantastic everyday water bottle and definitely lives up to the hype. Keeps drinks cold, holds a good amount of water, and works equally well for school or road trips.
