We now have six of these bottles. They work fantastic! We have not had one of them leak. I would think that, as in the one review, probably the only thing that it could or would be if it leaks is the white seal, but we have never had one come out of place. We've been using them for 3 or more years now. I plan to buy more because they are more trustworthy in keeping the drinks cold, easier to handle, fit in the cup holders in the car, and certainly, the ring holder at the top is extremely convenient. I am going tomorrow to see if there are more in stock because between my two granddaughters and I we use them everyday. The cups are washed regularly in the dishwasher as I feel safer in getting all the cracks and crevices clean because I drink milk in mine. I can fill it in the morning with milk and three or four ice cubes then have leftover at night time, put it on the shelf and in the morning finish it off. The milk would still be cool. I don't think I've had any cups keep my drinks cool as well.

These are the best water bottles ever, until the plastic tab on the front of the clear cover breaks. It's just a matter of time. both of the ones in the 2-pack broke in the exact same manner. They're great, just know that this will eventually happen and the replacement lids are as much as a new set of bottles.

These adorable water bottles keep water cold for hours! Even overnight!

Easy to fill, keeps thing cold for many hours. Doesn't leak

[This review was collected as part of a promotion.] Treally like the Ello Pop & Fill water bottles. The Power of the pop-and-fill feature makes refilling quick and easy. The Ergonomics are great because the bottles are comfortable to hold and easy to carry. Maintenance is simple since they are easy to clean and keep ready for everyday use. The Value is excellent because you get two cute and practical 22 oz bottles in one pack. In terms of Reliability, they feel sturdy and work well for daily use. Overall, I love the design, convenience, and quality of these bottles, and they are perfect for staying hydrated throughout the day.

[This review was collected as part of a promotion.] These Ello pop & fill water bottles are so cute and functional! The 22oz size is perfect for daily use,fitting easily into bag pocket.the pop-and-fill lid makes drinking and refilling completely hassle without leaking

The water bottles are cute and work well. I like the narrower base. The problem is the lid! We are not 3 full weeks into school and the clear snap over lid is broken on one! Now it is not spill proof and can't be used. They are cute, but not durable. I will not buy them again.

[This review was collected as part of a promotion.] I am never without water, so I was pretty excited that Ello and Influenster sent me Ello Pop & Fill Water Bottles complementary for testing purposes. I am so happy with how well made these water bottles are. They are made of stainless steel and BPA-free lid. The lid is so unique. It is leak-proof with a locking feature but also has a pop-to-drink flip top that covers the part where you drink. It has a wide mouth opening but still can work with a straw. I love that I do not have to worry about spills and mess with this bottle. The bottles have the cutest designs that withstand a dishwasher. The design is not simply printed on, it is a durable raised design. I love how thoughtful the design is. The lid and lock button matches the colors in the bottle design. The pack that I got had small flowers and plaid that are so beautiful to bring everywhere. I take mine everywhere. I love that I can throw it in my bag and not worry about leaks. I can also open the lid and drink with one hand when needed. The bottles hold a lot of water at 22oz. so I do not have to refill much, but the bottles are not too wide or tall. It is a perfect size. I love that these are dishwasher safe. The fact that it comes in a 2 pack makes my life even easier. When one is dirty or left at work or school, I know I always have the other. They clean so well and have held up great to both machine and hand washing. If you are looking for an affordable, durable, cute water bottle, this is it!

[This review was collected as part of a promotion.] These are so cute! I absolutely love the cheerful designs. The function is also pretty good. I LOVE the sturdy handle, straw option, and that it keeps beverages cold all day. I also like the locking function, however, I wish it was a bit sturdier as it is just a small piece of somewhere movable plastic. The leak protection is pretty good, thigh some water does get out. Therefore, I would call if leak-resistant. I also like the shape is it fits in most cupholders and that you can refill these without taking off the whole cap.

[This review was collected as part of a promotion.] I received these complimentary from Influenster for my honest review. The size of them is perfect. They're easy to fill and fit in any cup holder& backpack. They have the little handle to carry around or clip keychain/keys too which is great if you're going to the gym! I love the design too. They don't make a slurping noise when you use the straw which is also a plus!!
