[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.] 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.] These are amazing! My newest favorite water bottle! The colors are beautiful and match so good. But my favorite part is the straw. I love a straw cup but hate how they are not spill proof and this cup was able to fix all of that! The straw has a feature that allows it to fold away making it completely spill proof and that is such a unique feature I haven’t seen yet. The handle is also an amazing feature!The only thing that could make it better would be a rubberized boot. I highly recommend this is everyone!!! I will recommend again and again.

[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.] 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.] 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.] Thank you for allowing me to try these out! These cups are amazing! Keeps my drinks cold literally alllll day! Very durable, easy to use, I can hide the straw to keep it safe from outside elements, very portable, light, and easy to carry and take on the go with me! Cleaning my cups is super easy as well! Great color choices too!

[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.
