Review: Excellent bottle and worth the price! - I really like this water bottle. We have purchased five of them over the years and the most current purchase is replacing one that I’ve been using since 2019. There are several pros and the main ones are that if you fill it with ice, your drinks will stay cool for over 24 hours. We pretty much use ours for water so we don’t have to worry about ice watering our drinks down, but I’m sure if you put another drink in there like lemonade or a sport drink that it would stay cool even with less than a little to no ice. The second main pro is that you have two different types of lids: a straw type and the quick chug type. I use a straw and my daughter likes to drink hers with the big open chug style. The main con is with the flip up straw function, which is what I actually use the most. Sometimes a little bit of water will catch in the top of the lid after you close the straw, and it will spill out a few drops. It’s not very much and I’m kind of used to it so it doesn’t bother me much but it’s annoying at first.
Review: Perfect! - Great cup. My kids favorite color is purple. Keeps water cold. Comes with straw cap and extra straw + open spout cap. Great capacity. No leaks.

### ⭐⭐⭐⭐⭐ The best water bottles I've ever owned.
*by M***O on July 15, 2023*

I first bought the 64 oz. bottle a year ago, because I drink a lot of water at night and wanted a big bottle that would stay cold all night long and hold a significant amount of water. This bottle went above and beyond my expectations. I noticed the first time I put ice in it that when I went to fill it the following night, the ice still hadn't melted, after 24 hours. Amazing. That to me is the best thing about these, how long they can actually keep a drink cold, but it isn't the only great feature. The bottles are elegant and well designed. They're heavy duty and feel super sturdy. I dropped my 64 oz down the stairs trying to carry it with a laundry basket and it didn't dent or even really scratch. The bottles are super easy to clean, each piece of the lid comes off so you don't have to worry about scum forming around the straw. I loved it so much that a few months later I bought two more, the purple and black 32 oz bottles. My wife and I wanted to start making our own iced lattes during the summer, since they're like 8 dollars each now, and needed a good bottle with a straw that would keep our drinks cold throughout the day. I instantly thought to look up if they sold 32 oz bottles (size of a large Dunkin iced latte) and sure enough they did so I got them. They've been awesome! I work outside a lot and even In the summer my drink stays ice cold and the ice won't melt until long after I've finished it. Took advantage of the prime day sale and ordered another two (40 oz white and purple). They are extremely well priced compared to their competitors. It's just really refreshing to find a company that makes quality built to last products at a decent price. Can't recommend these enough.
