After washing my bottle out several times there’s white debris in the rinse water. The more I rinsed the more the white debris came out. It looked like paper

I'm liking the 26 oz capacity. Its not too small, not too heavy. The insulation is serious too - my water is staying cold for a day+. My intent was to get some sturdy water bottles with a flip top lid and get rid of all my old twist tops. I LOVE THESE

We really like these bottles. We've actually bought three sets of them. HOWEVER, the lids are a problem. Three times they have broken. One just failed and the other two broke when dropped about 2 feet out of the fridge door onto laminate floor. The bottles themselves are really sturdy and stay cold. The lids not so much.

This is my favorite water bottle, we use them all the time. I love being able to fill it with ice water and still have it ice cold when I get done with work and need a refreshing drink. It's perfect for hiking in the heat as well because it keeps your drink cold for a long time! The rubber band that snaps opens the lid did break but it's still easily used, I just hold it open with my finger. Love these water bottles!

I've purchased a total of 4 of these since the beginning of the year, one for each member of my family, because we absolutely LOVE these! HOWEVER, three of the lids have broken, the culprit being the little rubber O ring that causes the lid to flip. After less than a year, needless to say, I'm severely disappointed. LOVE the product, but can't use them anymore.

This is by far the best stainless steel water bottle I’ve ever purchased! The locking flip top lid and soft drinking split are my favorite things about it. Mine have gotten a ton of use and everything is in good working order. I recommend these to all my friends and keep extras in case I lose one.

These lids have a reputation for breaking and Zulu has non-existant customer service despite their lifetime warranty. They don't respond to their customer service email or the warranty form. Sam's Club came through with their great refund or replacement policy but I'd steer clear of these.

Unfortunately these ended up leaking right around the mouth piece, even when locked. And they do get dinged up pretty easily. On the plus side they do keep water cold and ice for about 8 hrs. my high school and junior high kids have been taking them to school for 2 wks now.

I have bought these for my kids for school. With all the covid stuff, water fountains at school have been shut down and they will need a water bottle. They have not used them yet, but they look pretty in the water bottle pocket of their backpacks! The were shipped really quick!

This bottle holds temperatures well as it keeps drinking water cool for many hours. The cap is really convenient with its slide bottom to change opening from drinking to wide opening for refilling. The cap also allows a carabiner to be used to carry on outside of backpack or bag. Will repurchase again if needed.
