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. Read more

Excellent size for a child or if you are looking for a smaller tumbler/sipper. Insulation is great, liquid stays hot and cold for a while. My child is happy with this! Read more

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. Read more

Great water bottle. I really like there are two lids and the loop to carry the bottle. I had purchased three contigo bottles in the past but the bottoms kept falling off making them unstable so I tried this one. It’s exactly what I’ wanted with no bottom to fall off as the bottle is one piece. I use it for water while working out and it does a great job keeping my water cold. I got the purple one; love the color. Read more

The ThermoFlask Insulated Stainless Steel Water Bottle with Chug Lid & Straw Lid 40 oz, Cobalt starts out as a decent value for the price. I paid $25.49 for mine, which is comparable to the Kodi brand 32 oz bottles sold at the local grocery chain. The bottle is a dual wall vacuum insulated design with an attractive paint color. That seems very durable and long-lasting. I did have concerns about the lid. You get both a straw lid with flip-top, and a dual "chug" lid. Those are just plastic, with a small rubber seal to reduce (not eliminate) leaking. The smaller flip top tightens down pretty securely, but the overall lid is very inexact when attaching to the bottle. There's no stopping point, so you feel like over-tightening is going to strip out the plastic. There's no metal threads on the top, just plastic. I haven't tried to see how tight it will get, because I don't want to ruin it. When I tightened it as much as I felt comfortable, it still leaked. Going on a long camping trip, the bottle held up well. I had it in the side pocket of a backpack, so it was not tilted or challenged in terms of leaking. It kept my cold drink cold all day. The insulation works well, and overall I was very pleased with it. I'm still not 100% sold on the long term durability or sealing of the plastic lid, but for the price it was a nice, big, insulated bottle that does most things well. I would probably buy it again. NOTE: The product title and listing details clearly state "Dishwasher-Safe Reusable Bottle & Lids," but you can see where it says "Handwash Only" on the bottom of the bottle. Read more
