[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 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.] 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.] I received this product from Influenster for my honest review. I love these water bottles. Their design is very good plus it’s clean very easily . And it’s 100% non leak bottles. It makes ur water cold for a long time . Definitely recommend it

[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 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.] 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 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 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.
