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.

Who wants to handwash their water/drink container! Not me! Love these!!!

The clear plastic latch on the lid broke after using for two days. The features of the bottle were great though. But returned and didn't trust getting new ones.

I love these water bottles. They are the perfect size for every cupholder they have been dropped and do not bend. I love the quick fill feature without having to worry about dropping the straw. However, the top lid that also holds the handle is easily broken. Both bottles broke within one month of using them. Since the handle is tied into that top lid, it makes carrying the water bottle, awkward. I gave this a four star because I really truly love everything about this bottle except the top lid and handle.

These are a great idea but something is off in the final process. Bought 6 of these cups and three of the plastic lids broke evidently due to poor construction. The little tab by the button for the pop lid breaks randomly. You don't have to drop it, just use it for a little while and it breaks off. Great design with a major flaw.

These are the worst water bottles ever! They leaked most of the time, the top broke off easily AND the silicone spout part gets all moldy. Please bring back owala at sams.

My kids took these to school for only 2 days because one of the lids broke when it was dropped once. My main reason for giving it one star is because they somehow open and leak inside the backpack.

I honestly cannot understand all the negative reviews. These water bottles are great. They keep my beverages cold overnight (I keep them on my nightstand) and during the day. I haven’t used them for hot but they were so amazing for cold that when they went on sale I bought 4 more bottles (2 boxes) in the club. As for the leaking I have never had an issue and one day decided to test it out every which way but loose and it never leaked. I think the problem people are having is that the white rubber piece that creates the seal comes loose sometimes. I am not sure why but all I do is pop it back in and then it goes right back to a watertight seal.

Bought 3 sets of these water bottles and loved them at first - would have given them 5 stars. Filling without having to remove the lid is convenient and it is easy to open and drink one-handed. Unfortunately, after less than 3 months of daily use, 3 of the bottles leak regularly from the "fill" junction (re-seating the gasket doesn't help for long) and 2 of the plastic spout covers have broken, which means those 2 bottles also leak if not upright.

it keeps your drink cold all day/all night, but if you drop it, it will spill. Theres nothing to prevent the top from popping open. Also, the rubber gasket slips out of place and you dont know until you lift to drink and it pours on you. I have four and I wouldn't buy again.
