[This review was collected as part of a promotion.] These water bottles are great. They don’t spill or leak even when thrown into a bag or the back of the car. I like that it still has a straw but that you can close the straw off. The handle makes it easy to carry more than one or one with other things. Great product that will replace my other water bottles.

[This review was collected as part of a promotion.] I got the charcoal and cream colors, and they are beautiful neutral colored tumblers! I really like the retractable straw feature which prevents dust or bugs from getting into the straw. It’s a little on the heavier side but the handle makes it easy to carry. It does keep my water cold so I have no complaints! The slim bottom also fits inside my car’s cupholders.

[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.] 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’ve tried more tumblers than I care to admit, but the Ello Oasis 30 oz is officially the one. The 30 oz capacity is big enough to keep me hydrated, but not too bulky or heavy. The handle is comfy to grip, and it fits in my car’s cupholder perfectly. But what really sets this tumbler apart is its “Hide-A-Straw” technology — lets you neatly tuck the straw away keeping it clean and preventing leaks allowing you to toss your tumbler anywhere. And yes — it is 100% waterproof. I’ve tossed this thing in my work bag, gym bag, and even on the passenger seat of my car, and not a single leak. Not even a sweat ring. It seals up tight and stays cold for HOURS. I’ve had ice still rattling around at the end of a long summer day. Pros: * Legitimately leakproof * Hide-A-Straw = genius * Keeps drinks cold all day * Easy to clean (straw and lid come apart) * BPA-free and dishwasher safe Cons: * Only a few color options — would love to see more! * Straw doesn’t work great with thicker drinks (smoothies, etc.) Verdict: If you’re tired of leaky tumblers or flimsy straws, the Ello Oasis is a game-changer. Sleek, functional, and built for real life. HIGHLY RECOMMEND

[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’ve been using my Ello tumbler and I have to say, I really like it! ✨ It keeps my drinks cold for hours and never sweats on the outside, which is such a big win when I’m on the go. The size is super convenient to carry around, and I love the cute, modern design, lovely colors, it definitely feels stylish while still being functional. Plus, it’s BPA-free and dishwasher safe, which makes cleanup way easier. One thing that really stands out is the straw design. The top part is made of hard plastic while the bottom is soft, and it’s attached in a way that you can easily pull it down using the pull bar on the lid. It’s such a clever and convenient feature! That being said, the tumbler is a little on the heavier side, and sometimes it can be tricky to clean thoroughly. But overall, it’s a high-quality tumbler that looks great, keeps my drinks icy cold, and has some really innovative features. 💧

[This review was collected as part of a promotion.] We’ve been using these cups for about a month now and find them to be durable and convenient. When filled with ice they keep drinks cold all day. It’s nice for iced coffee as well as water. The lid has a retractable silicone straw which folds in when the lever on top is closed. This is nice as the straw stays clean and germ free when being carried around. I removed one star because I do find the lids are difficult to clean and I’m concerned they could become moldy. The handle makes it easy to carry or to be hooked on to something.
