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!

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.

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 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 really liked these bottles until the rubber ring inside the bottle got loose and makes the bottle leak. My laptop got damaged because of the leak... I liked the design that I can sip and drink, and pour without having to open the whole water bottle. However, after some time of use, the ring rubber by the cap started coming off causing the bottle to leak. I had to fix it often and keep checking. One day, the bottle leaked and spilled water, damaging my laptop.

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.

My teenager was loving his new bottle despite a little leakage, and then he dropped it while sitting in class. The top broke, and water went everywhere. The top was locked when it happened and still locked after. I would not recommend purchasing.

I love Sam's Club, but these are the worst things I've ever bought from Sam's. Ice melts very quickly. The tops are overly complicated made of many cheap plastic pieces. It's a water bottle for god's sake!!! Can't even think of what I can do with them now except give them to someone I don't like.
