[This review was collected as part of a promotion.] I really like this tumbler—it’s sturdy, easy to clean, and the handle makes it so convenient to carry around. It keeps my drinks cold for hours and doesn’t leak when sealed properly. The size is perfect for daily hydration, and it fits well in my car cup holder.

[This review was collected as part of a promotion.] I cannot say enough about how fantastic these cups are! My kids take them to school and it’s finally a straw cup, with a handle, that doesn’t leak! They’re sturdy and solid, and keep beverages cold for several hours. They’re convenient to take for a day in the car or a day at school, and the colors are beautiful! These tumblers are so great, that my teenager hasn’t slapped a ton of stickers on it yet because she says it’s too pretty! We need more!!!

[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.

[This review was collected as part of a promotion.] The perfect pair of Stainless Steel Tumblers. These are not only super easy to use and optimized with their straw technology, but they keep my drink cold or hot far longer than most other Tumblers. As long as the straw is closed leaks will never be a problem. Overall, my new favorite drink holder.

[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.] 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.] Truly love these tumblers. My new favorite! The fact that they have a handle, a straw, and size checks all of my boxes. My favorite part is the innovation behind the straw. Keeps germs away and my drink cold!

[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.] LOVE LOVE LOVE. I absolutely love this tumbler. I love the color options and I love that it has a retractable straw. My drinks stay cold and didnt experience any leaking ir spilling. I would recommend thus bottle over any if tbe current top trending bottles. The straw design alone makes it above them all!!

[This review was collected as part of a promotion.] This is my new favorite water bottle! I love the size, not quite as bulky as a 40oz bottle. It also fits perfectly into the cup holder of my car. My two favorite features are the handle and the retractable straw. I actually like that the exposed part of the straw is plastic and the straw extension in the cup is silicon. I feel like the end of the straw you drink from is more durable. And, I like being able to throw it in my backpack when it's closed and know it's not going to leak. I prefer a handle design that allows you to carry it from the top, instead of holding it from the side, so this is great. It makes it easier to carry when my hands are full. The cream and black are great neutrals! It's fairly easy to clean since the straw component comes apart. I live in the desert, so insulation is a hit or miss sometimes. But this one seems to do a decent job of keeping my water cold/cool, even if left in the car for a little while.
