difficult to clean

while it does keep ice all day, my problem is it gets moldy where the straw retracts into the lid and is extremely difficult area to clean. had to use a qtip and just keep at it. I won't purchase again.

reply from Ello Customer Support

Hello Rebecca! We're sorry to hear that you find the Oasis difficult to clean. We recommend thoroughly washing and drying your tumbler after each use. The Oasis lid can also be sanitized on the top rack of your dishwasher. Additionally, you can clean the tumbler and lid by shaking a mixture of ice and salt inside of the tumbler, then rinsing well. For storage, we always suggest to keep your tumbler unsealed when not in use to minimize moisture buildup. If you find that you are still experiencing an issue with mold, please reach out to our support team at support@elloproducts.com and our support team can help get a replacement lid sent out to you.

Doesn't work as expected.

I wanted to like these, but it's just not happening. In order for the straw to retract, the cup has to have little ice (not even close to the fill line) and the ice has to be separated. Otherwise, the straw gets blocked by the ice. At least that's what I think is happening. Whatever it is, I don't like it.

Retractable straw is very convenient

[This review was collected as part of a promotion.] These tumblers are made sturdy and durable. Bring 30 oz, they hold quite a bit. It has a comfortable grip, is spill proof and the retractable straw is very convenient and on the plus side, protecting it from germs. It's very simple and easy to clean. It is stainless steel and well insulated, keeping your drink cold for quite a while. It fits in most cup holders also.

Not for hot or carbonated beverages

Love the design, however the store description doesn't align with the packaging. Store description says this cup is for hot and cold beverages and the packaging says “Not for use with hot or carbonated beverages.” I give it 2 stars since I purchased it with my morning coffee in mind and am disappointed.
