[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 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.] I love the concept of these cups and that they keep your drink cold for hours. I fill it up with ice before I go to work and it's still full of ice and cold after my shift. I also was happy to see you can close the straw opening but, my issue is with ne filling my cup with ice, it's a struggle to actually close the straw hole since I have all the ice in there. Is it a design flaw? Not necessarily. It's because I load my cup with ice. If I cut back on the ice, it would make a difference.

[This review was collected as part of a promotion.] These cups are not only cute but super useful! They hold a lot of water! And they are spill proof! They are also super comfortable to hold as there is a resting spot for the thumb. 10/10 would recommend!

[This review was collected as part of a promotion.] The Ello Oasis 30 oz Tumbler is a stylish and practical option for everyday hydration. The comfortable handle makes it easy to carry, and the retracting straw is a convenient, hygienic touch. Its insulated stainless steel design keeps drinks cold for hours The soft, silicone straw tucks away with a quick turn of the lid dial, making the lid leak-proof and keeping the drinking surface clean when not in use. It’s perfect for school and on-the-go! No spills in bags with 100% leak-proof locking lid. A solid, well-designed tumbler for anyone who wants a large, easy-to-use cup for daily use. A little bit heavy when it is full, but much more better than other 40 oz ones.

[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.] 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!

Beautiful tumblers but I'm not a fan. They do not hold the ice for a day. I didn't realize that they have a fold-down straw. If I had, I would not have purchased them. The straw mechanism and the ice get in each other's way. It's unfortunate because the light purple with daisies and the light green gingham check are both beautiful patterns. I may see if I can find a different lid to fit or try to take the mechanism out. Not holding the ice is still a big issue for me though.

[This review was collected as part of a promotion.] The colors of the blue cup is absolutely stunning. I love the trigger for hiding the straw too. It’s leakproof and holds a good amount of water. Feels like it’s a really good quality, but the lid is a little cheaper feeling. Overall, though, these are really nice.
