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.] 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’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.] 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.] 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.] 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.] 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’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
