[This review was collected as part of a promotion.] Love these! One of my favorite aspects of it is that they're car cup friendly. I grab these before leaving work and using them for in my cup holder is amazing. They're heavier weight, but not heavy enough to impact carrying them around (the sturdy handle also helps). The inside is stainless steel which helps keep my hots hot and colds cold. I also love that their car cup are dishwasher safe. Overall, I'm extremely pleased.

[This review was collected as part of a promotion.] I got right in these and started using them right away. Love that the straw in hidden for anti spill! Plus it keeps things cold/hot for 24hrs! Also enjoy that it fits in cup holder. They are big, so make sure you have room for the handle :)

[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.

[This review was collected as part of a promotion.] I cannot tell you how much I LOVE the Ello Oasis 30 oz tumblers! They are so worth the money. They are sturdy and so very nice! I love the leak proof retractable straw the most but I also love how they feel like they should be a thousand dollars. They just feel and look so nice. It's also so awesome that they keep your drink cold for up to 23 hours! That's amazing! I am very happy with these and I really love that they came in a 2 pack so my husband gets one too. They are perfect for our road trips cause they fit perfectly in the cup holder

[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.

[This review was collected as part of a promotion.] These cups are lightweight, stylish, and easy to use. The 30oz size is perfect for staying hydrated throughout the day. They feel well-made comfortable to hold, and are easy to clean. Great for everyday use at home or on the go.

My favorite part of these cups are the retractable straw it's really nice to l be able to close my drink without taking my straw out you just flip the switch . These cups keep my beverage really nice a cold all day long . I love these colors on the two I received one is a beautiful cream color and other purple with bows my favorite one is the cream colored one these are going to be perfect for taking with me to the beach soon . I'd highly recommend this product. They are nicely made .

Saw this in the club and immediately bought it for the lemon design. I love that the straw is retractable to protect against germs over those straw covers. Very happy with my purchase.
