ZULU Powerfill Pro 40oz Stainless Steel Sip or Chug Water Bottle, Black

I have bought so many different flasks trying to find ones that work well and are easy to clean. My biggest issue with buying bottles like this is I'm always worried that they're going to get slimy and get mildy buildup on the inside, which makes me feel kind of iffy about using them. These ones come apart so easy. The straw detaches but then when you put it back in it stays in place which is fantastic. It keeps your drinks cool for most of the day which is awesome and it's very versatile. It comes with two different attachments to make it. You can take smaller sips or it has an attachment that has a bigger hole in it so that you can drink more. The lid is awesome because you can press a button and it unlocks the top so it just pops open. There is also a switch on the side that you can click that locks it in place so that it won't open. It's the perfect size and fits in most cup holders and the colors are awesome. It's dishwasher safe and I haven't had any issues with this and the handle on it also makes it very easy to carry. I thought multiple of these and I recommend them.

Absolutely a great buy! Highly impressed for only $21.50. Very well made! Equal, if not better, than all the popular name brands like Swig, Yeti, Brumate, etc. High quality design/print that is slightly textured to the touch. Rubber/nonslip bottom, removable lid and straw, flexible zip spout, easy to attach the water bottle to a backpack, purse, etc. Super cute navy gingham! Keeps drinks cold, hand wash recommended.

I love this waterbottle its so perfect and easy for me to keep track of how much water I'm taking in. I did read the reviews on the spilling it can cause and it is true, I found if you fill just before the actual twisting part you should be fine and they're won't be any spillage. With that being said I wouldn't say its a true 32oz just because of the underfilling but thats no problem for me because I tend to have a little sip and refill it again lol. The handle for now is good it does seem like the little bolt holding might fall off but for now its good. The taste and temperature retention is SOOOO GOOD. I have filled this waterbottle up at work with cold water and I have come back to it late at night and the water is still cold like if I just filled it up. From experience I would say 5+ hours I cant really say more than that because the water doesnt last as long lol. Overall very happy with this purchase I highly recommend to anyone needing a waterbottle, I myself have been looking at their bigger bottles because I'm drinking alot more water and I want to better keep track of my daily intake. Again solid purchase and highly recommend.

Bought this for my husband and it’s perfect for someone who doesn’t like to drink from a straw. It’s durable, has an easy way to pop open the lid and fill the water bottle. The size is ideal and the color is nice with an affordable price! Overall, a really great bottle to invest in!

Replaced my last bottle that I love and miss. Its been great though, probably 2 yesrs in and it holds cold liquids well for a few hours. Id say with ice, youll make it a full 8hours, otherwise just cold water out thr fridge Id give it maybe 6. Despite me dropping it, its never dented and surprisingly nothing is shattered off. Just today the spring stopped springing back, but this is after 100 or so drops so Id buy it again. Im shocked the clear plastic bit never fully broke off but it did shatter a little, still holdin on though.

I'm super picky about my water bottles. This one is my new favorite! + The chug spout is great! + also comes with a straw insert (if you're into that sort of thing). I like that you can go chug or straw without having a separate lid. It's really easy to change from one to the other. + flip top for refilling is super easy. I only need to unscrew the lid for cleaning. + cleaning is easy. + keeps my water cold all day. + the handle is easy to grab. + grippy bottom stays where you put it.

My new FAVORITE drink tumbler. The size is just right for a full 16 oz water drink with lots of ice. I love the grip on the bottom. The temperature inside keeps my ice frozen all day long. It’s versatile and durable. The handle is great and I LOVE that I don’t need the straw! I was looking for a spout and this is it. I’ve wasted so much money looking for this and I’m so happy I finally found the perfect one for me! And I Love Love the purple. Perfect! Everything tastes great!

This is the best stainless steel bottle I've found for the price. So why only 3 stars? This is my 2nd Zulu - I had a 24 oz Powerfill Pro and now this 40oz version. Both did a terrific job of keeping the contents ice cold for many, many hours. About 6 months after purchasing the 24oz bottle, it appears to have lost the 'vacuum' insulation. The outside of the bottle got ice cold as soon as I put water and ice in it, and the ice would melt within a fairly short time. I contacted Zulu and they said it was probably the o-ring in the lid, so they sent me a new lid. Sorry, Zulu, but if the bottle is getting cold on the outside and there are no leaks, it's NOT the lid. It's the insulating factor of the bottle. Thankfully, these things are inexpensive, so I order the 40oz bottle. I've had it (almost exactly) 6 months, and the same thing happened. Bottle began getting cold on the outside and the liquid inside warmed up to room temperature over night. I'm not sure if these bottles begin developing air leaks (neither of my bottles had been dropped or mishandled) or if there's some other reason they lose the vacuum. Anyway, I don't want to believe this is planned obsolescence - I really like the design in every other way. I just am irritated that I have to replace this thing every so often. So, three stars: Excellent use design. Not so good longevity. I'll buy one more, but if this happens again, I'll be looking for a better brand.

Ordered this bottle after trying the 40oz zulu which had no issues, I received this 64oz bottle in the wrong shade of white described in the ad also the bottles top cap keeps opening whenever I fill it up i do not recommend anyone to purchase this bottle since you will face many problems with the cover coming off and spilling everywhere.

muy buena, aveces es difícil abrir con el botón

Keeps my drinks cold all day. Even left it in my car on a 40°C day and water was still ice cold at the end of the day

Awesome and makes me hydrated every day, its pretty expensive but worth
