[This review was collected as part of a promotion.] These cups are very fashionable and keep my water cold for a long time. They have a nice handle on top making it easy to carry. The retractable straw is a fun feature that I've never seen before. I like being able to keep germs away when I'm not actively drinking from it. I also tipped it upside down when the straw was in and it didn't leak a single drop. The cup did scratch fairly easily and I feel like the straw mechanism is a little tricky to make sure it's clean. Overall it's something different and works well.

[This review was collected as part of a promotion.] I received the Ello Oasis 30oz Tumbler free from Influenster in exchange for my honest review, and I’ve been loving it! It keeps drinks cold for hours and hot drinks stay warm just as long. The size is perfect for all-day hydration, and the design is sturdy and durable without being too heavy. I also like the sleek look and the lid seals well to help prevent spills. Definitely a great tumbler for everyday use or travel!

[This review was collected as part of a promotion.] I thought I would love it like my other ello bottle but I don’t.i like the design but im not impressed and i wont buy it again.love the hiding straw but its hard to clean underneath.no way to get around the hole of the straw since the straw can’t not be removed for wash.the inside silicone straw can’t remove but since its silicone it will be easy to get mold.i got the purple so it will be hard to see it. Love that it fits the car cup holder but hard to be hold by hand since i have small hand. The handle on the top of the cup is stiffed since it’s brand new.

[This review was collected as part of a promotion.] This beverage tumbler is actually amazing. Great quality to keep beverages cold. It has a great attached handle for ease of carrying. Easy to disassemble for cleaning and nice colors. But my absolute favorite part is the hideable straw enabling you to completely close the lid for safety and to prevent any spills. Great product.

[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.] As someone who hates the straw sticking out (for hygiene reasons) and needing to buy a straw cover, I absolutely love this design! It’s so cool! It’s easy to use and is 100% leak proof which I love! The underside of the lid is a little complicated to clean because of the straw mechanism, but I hand wash so it’s not a big deal. The cup is apparently dish washer safe though which is great! My only other nitpick is that I’d love if it had a rubber bottom so the metal wouldn’t be right on a hard surface.

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

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.

[This review was collected as part of a promotion.] Such pretty tumblers! They feel very durable and nicely insulated. The hidden straw feature is also a very handy feature. I love everything about these tumblers.

[This review was collected as part of a promotion.] These retractable straws are so neat. These cups stay cold all day, I hand wash mine to be safe. I love the design of the cup. It’s very durable and leakproof.
