[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.] I'm absolutely in love with these cups. I love the fancy little straw. These keep my drinks nice and cold by the end of the day there is still ice in the cup. Super each to take apart and clean holds a whole can of Mountain Dew. And the design on the blue one is super cute!

[This review was collected as part of a promotion.] I love using these Ello Oasis tumblers daily and they are quite convenient. The hidden straw design is very practical and if I'm using it outside don't have to worry about the dust also. I haven't had any leaking issues so far. They keep water cold for a long time and feel durable in hand. The size is a little large but that's expected for a 30 oz tumbler. It's a good buy for everyday use and travel.

[This review was collected as part of a promotion.] This is a great cup for travel. It has a handle for easy carrying and it fits in cup holders. The cup is easy to clean, it comes apart completely and is dishwasher safe. The straw goes down and is covered when not in use which is great so you don't get anything gross in your drink. One of the cups did leak from the top when tilted, however the other one did not. Still loving these cups!

They leak!

Don't buy. It doesn't keep cold for long and the straw mechanism broke within 3 days. Its completely useless now

[This review was collected as part of a promotion.] I love these cups! They are quality and they keep my water cold all day! And they literally keep me hydrated because I have to have the cup with me wherever I go. Cleaning isn't that bad either!

[This review was collected as part of a promotion.] Really cute cups. I like the plain white one but the bows are cute. The built in straw that ca be hidden is so awesome. I love it. Keeps it clean. And holds a ton of water

[This review was collected as part of a promotion.] My setup is simple but I love my cup. Value is great can't com and love the design and material of it. Very strong and long lasting. Functionality is excellent
