Love that there is a lid lock feature and the top flips up for refilling without removing the straw. Cools for long periods (made it through a hot september disney day). The only negative is if they rub together with another ello bottle, the coating scrapes easily.

This was one of the best impulse buys I have ever done. We use these bottles every day. The flip top for drinking with the straw makes drinking water simple. I love the easy fill spout. The twist off top for cleaning works perfectly. The water stays cold. They are easy to clean. They are a little too big for standard car cup holders but even that we make work.

This is my 2nd purchase for these water bottles! My adult girls love it! It’s designed like a sippy cup! But the water flow is amazing. You don’t have to tilt the bottle to drink from it, a straw is included! It’s spill proof. Just press the button to flip the top to drink , then flip the lid to add ice and water, no need to unscrew top. Keeps drinks cold, ice last all day!! Highly recommend this product! It will Not disappoint!

I like these more than my Stanley. Perfect for myself and my 6 year olds many activities with sports. Heavy duty, easy to use, perfect for all!

Great design, keep in mind it can be used keep cold water only, not hot.

The water bottles leak. After about 2 months of use, the lids break where they attach to the plastic ring. The replacement lids are not cheap and are expensive. Not worth the money.

The is a very mediocre water bottle. It's by far not the worse water bottle I've ever had, but it's filled with flaws. It's got many great benefits, but unfortunately the flaws over come those enough to leave a bad review. The Good: * I love how i can easily fill it with water, or take a big gulp by just popping the top open, it makes use much easier than the screw tops. * The lid is filled with convenience features - easy to pop open straw access - keeps the top clean and easy to access for use - keeps the bottle from leaking for the most part (not perfect by any means) and it's lockable... * Easy carry handle - lets you easily carry the bottle around, or attach to a carabiner clip etc. THE BAD.... * It leaks - it leaks from the seal between the cap and the bottle, it leaks from somewhere inside the cap, when you fill it to high, then put the cap on it pushes water out over the edges - best bet is to use it only for water, and keep a paper towel on hand. * The top that keeps the straw sealed tight when not in use is held close with a TINY plastic tab - when this tab breaks, you can not close the top, which means you can't seal the straw port - which means ANY time it's not perfectly up and down - IT POURS out. This is a huge design flaw - the whole bottles functionality relies on a tiny plastic tab. * Speaking of straws... the straw is constantly falling out from the hole in the lid - meaning you go to take a drink, and you only get air unless you tip the bottle. I have to open the cap and re-attach it about once a day which is frustrating.

I wanted very much to be the solution to the water bottle needs we had as a family of five. I purchased three packs. I've had nothing but trouble this whole time. the leaks that I've had to deal with have been horrendous. airplanes, backpacks, cars, all drenched because of these water bottles. beautiful concept, sleep design, but the number one thing that should have been taken care of from the beginning is the number one reason I'm returning these.

I would have rated it 4 stars but the cover part of the lid breaks, and we cannot figure out how or why, making it useless - straw exposed and now way to close it. Of course Ello offers new lids for $7 each, but come on, my Owala bottles are still working. We have not had leakage issues as long as the bottles are not overfilled.

I bought these for my kids to use at school. I wanted to love them but the lids broke after a few weeks which rendered them useless! We also had trouble with them leaking, the gasket on the lid would frequently fall off. Another problem was the straw on the inside kept slipping out which meant they couldn’t get a drink without them sticking their dirty hands in the water to fish it out and then reattach it. Great idea for a water bottle but very flawed design.
