[This review was collected as part of a promotion.] These ello oasis cups are so cool! The design is cute and sleek made of metal making them durable keeping my drink cold for several hours on end. The cup is 30ozs holding a lot of liquids great for theme park summer days! The weight for a 5-year-old given the size is heavy with liquids, but have no fear they make smaller sizes perfect for children. I completely had the cup upside down, and NOTHING leaked. Even when i had the straw opening open , the straw was showing (but) not retracted again no leaking. It fits perfectly in my car cup holder. These are perfect for everyday use going to attractions indoor and outdoor, perfect for road trips, and perfect for all members of the family. The top piece doesn't need to be completely taken apart for cleaning. Dish wash safe. I suggest getting pipe cleaners to clean retractable top piece of the straw, which is hard plastic. I did notice the mechanics weren't as smooth when retracting after dishwashing first time despite following instructions suggested hand washing for longevity. Overall love this product.

I love this tumbler. It has a handle which makes it easy to handle. It keeps drinks cold, still ice in cup in the morning. Pretty & fits perfectly in car cup holder.

Pretty and wonderful tumblers for pool and beach! No water gets in or out which makes it perfect for beach and pools! Keeps drinks cold for a long time, but maybe not as long as a Stanley. Gave them to all the women in our family for Mother’s Day.

I love my water ice cold and this tumbler keeps it icy for well over 24 hours in warm weather... I am extremely pleased.

Absolutely spill proof. These are some of the best tumblers I’ve ever bought. Plus they are so cute.

I absolutely LOVE these tumblers! Not just super cute, they serve the purpose I was looking for. I am able to close the top and throw them in my backpack that I carry to work without worry. They are smaller than my usual 52oz so I just use 2 cups if needed. The issues I had before, were the 52oz is super heavy and my shirt was always getting a little wet as it sloshed out the straw hole when walking into the building. Now I'm hands free with all cups in my bag. Another benefit is since the lid screws on, I no longer have the issue of my cup falling off my desk and having a huge mess to clean up when the lid pops off. One minor flaw that is not a big deal if you are expecting it, often when I raise the straw for the first time in a full cup, a small amount of liquid comes out of the straw and lands on the lid (think of those little fruit cups your kids have you open). Now be mindful my cups are laying down in my bag and not stsying upright after I fill them. Again for me this is super minor and worth the benefits I'm getting. All of my teacher friends want one now.

When I purchased this, I didn’t realize you had to use the straw - no way to just drink from the side like other cups. I have gotten used to it now and actually like that the straw comes up and down. The only drawback is with ice in the cup. Sometimes the ice keeps the straw from going down and once in a while up. The other thing I like is that it’s a bit smaller than my previous cups (30 oz vs 40) but I find I drink more water now. Overall, the only thing I didn’t like was that it went on sale right after I paid full price 😜

Love the fact that the straw is not constantly exposed. The only issue I have is sometimes it’s hard to get the straw in when you have ice in the cup as the straw is so flexible. It keeps beverages cold all day.

[This review was collected as part of a promotion.] First of I do love the design of these water bottle. I really love that the straw is retractable and the bow cup is adorable and my daughter actually already claimed this one. Where my issue lies is I LOVE ice cold water and I LOVE when my water bottle keeps the ice from melting. Most of my water bottles I can put ice in at night and there is still some in the cup in the morning keeping my water from getting room temperature by morning but rather staying very cold and these cups just aren’t as insulated as I would like. They do a good job during the day when I am constantly drinking water but just don’t meet all my needs for this to be a holy grail water cup.

Waste of money, Be careful About new products at These big stores. Cute design on the outside but it is only an expensive cup. it doesn't keep anything cold for more than a few hours. Too narrow, it's a knock off of the ones That actually work. The straw concept is cumbersome and if you don't want to use it, There is no other top?
