[This review was collected as part of a promotion.] These cups are some of my favorite products I've received to test. I love the retractable straw so much more practical than a Stanley cup, the leak proof design and handle makes it convenient for the kids or hiking trips, and it keeps water cold all day.

[This review was collected as part of a promotion.] I got the Ello Oasis Go 30oz tumblers and I really love them. The design is super cute and feels higher quality than a regular tumbler, and the straws aren’t just basic clear ones, they actually look nicer. I love that they’re truly leak proof, so I don’t have to worry about spills, and they keep my drinks cold for hours. On top of that, they’re dishwasher safe, which makes cleaning so easy and they fit perfectly in my car cup holder, which makes them super portable. Honestly, they’re sturdy, practical, and look great perfect for everyday use!

[This review was collected as part of a promotion.] I received this product from Influenster for my honest review. I love these water bottles. Their design is very good plus it’s clean very easily . And it’s 100% non leak bottles. It makes ur water cold for a long time . Definitely recommend it

There is no spilling and with ice in the bottle the straw won't come out . The straw on one bottle already broke after a week of purchase

I really love the water bottle. The lid broke on the straw mechanism. Is there any way to purchase a replacement lid for them?

These work great for daily use. My old cup kept leaking but these don't. Tipped them over all kinds of ways, holding up well so far.
