[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.] 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.] The Ello tumbler has a tapered base and a retractable straw mechanism. Its swinging handle makes it easy to carry, and it fits conveniently in my car's cupholder. The retractable straw mechanism is quite impressive. It uses a sliding system that adjusts the straw to your desired height. When you fully rotate the mechanism, it seals over the straw to prevent spills. At first, I thought this mechanism would be hard to clean. However, the straw is removable, and you can rotate the mechanism to simplify hand cleaning under the cap. Personally, I still suggest using a dishwasher to ensure no residue is left behind. I've used it for water, pre-workout drinks, and protein shakes without any clogging or leaking problems. Only time will tell if it lasts long-term, but I'm really impressed.

[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 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.] 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 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 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.] 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.

[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!
