Love these! I'm definitely addicted!
5 out of 5 stars
Love these! I'm definitely addicted!
I never understood the Stanley craze until I started buying these bottles. I bought my first in 2022, and now I have a full on collection of them! (And just bought another today LOL). In my defense, I take 2 with me to work daily, and sometimes need another 2 for the next shift if I'm working a double. (One is for a caffeinated cold beverage, the other is always for H2O... and I'm a snob and only drink filtered water from home with ice made from filtered water). Having more bottles means that I can go a few more days before washing all of the used ones! First the negatives: as pretty as the "aurora" color is, it is a different texture and scuffs/scratches very easily. I have not had this problem with any of the other colors (although the rose gold is a slightly different texture as well). I have broken one carabiner clip on a straw lid, but I tend to fidget with them when stressed/bored so not unexpected. The bottom of the bottles can be a little slippery depending on the surface - I bought 2 silicone boots to negate this. Now the positives: I like my fluids ice cold, and each of these bottles keeps my drink cold with ice frozen for about 36-48hrs depending on the outside temperature. I haven't tried them with anything hot at this point. They never spill, as long as I actually close the lid correctly (I only use the straw lids... not the other two that each bottle comes with). I like that the straw lid folds down, which is why I don't have more of the copilots. They are easy enough to clean with a bottle & straw brush. I do admittedly switch between them daily, but no signs of mold growth in any of them, ever. The bright beautiful colors make them stand out and prevent them from "walking away" with a coworker "accidentally". They do not make noise when drinking and the separately bought silicone boots keep them silent on the desk, but honestly are not necessary - I just prefer them. The brand also has a paracord handle that works fine, but I don't typically use the one I bought. For reference, the attached pic is a 22oz elemental grey, 32oz blue waves, 40oz dark night & bubble gum & aurora, and then 40oz copilot in rose gold. I included a pic of a scratch on the Aurora from one single trip inside my work bag. The others make the same trip daily (and have for 3 years now) without a single scuff.

    This is a great flask that’s very durable and flexible.

    This is my second flask from this same company and I’m always impressed by the quality. My original 1 gallon flask lasted me for years and was very solid. I went with this smaller flask because it’s much easier to carry around while still holding a good amount of water. During the summer in the peak heat it always keeps the water crystal cold and it helps tremendously for my outdoor job. I’ve always loved the colors and designs and the three interchangeable lids are a game changer for me.

    I have had the bottle for only about three days but so far I am very pleased. I like the fact that it holds a full 16.9 oz water bottle and holds the cold temperature for quite a long time without ice. I do like the assortment of lids that are supplied. I prefer the straw for cold drinks and the flip up spout lid for hot drinks. the build quality seems to be very solid. I also liked the wide variety of color options. The handle makes it easy to carry and has a small carabiner of sorts on one end that I have not tried yet but looks solid enough to hook on a backpack, belt loop or whatever. I like that fact that it fits nicely into the cup holders on my vehicles. The price point is very reasonable for this build quality but time will tell on that point. I would definitely recommend this bottle and will most likely purchase another one.

    This is a great water bottle with one downside.
    The 40oz bottle does NOT fit into a standard vehicle cupholder. I have not found one vehicle with a cupholder to fit this (even a minivan), which is honestly a pain. Top occasionally leaks, so I have to be careful where I keep it in the car so it doesn't fall over and drip everywhere.

    For positives, I love the color, the different tops that come with the bottle, and it truly does keep my water COLD all day. I prefer the pop top; it is quick to open and easy to clean.

    Rating the 40oz 4 stars due to leaky cap and incompatibility with standard cup holder. Would rate 4.5 if I could. Overall, would buy again but in a smaller size.
