We have had 4 of these. Lids don’t leak, but the rubber inside the lid does give out. I am thinking that I put them in the dishwasher. So that’s not going to happen anymore. At least the lids are going to be hand washed. I did have one lid on our first set completely break, but had it for a few years, was used a lot.

I've been searching for the best water/sports bottle for a long time. The Zulu is by far, Simply The Best!! it has just 3 parts!! I'm a huge sweet tea with lemon fan so the detachable bottom lets me use 1/4 slices without them getting stuck, the middle is stainless and double walled so everything stays cold for hours, and the lid is fantastic it pops open every time, the soft spout doesn't hurt my teeth or lips, and the lock doesn't fail. It doesn't leak which means I can lay it flat on my bed or couch without worry. Did I say just 3 parts? NO straw to clean, NO spout to clean, which means NO GERMS!!!! I do NOT have to worry if I've cleaned it well enough. I've thrown out every other bottle I've ever purchased, and that's been 7.

This is the best stainless steel water bottle I’ve ever used. I love the soft silicon drinking spout and the lid lock. And even when the exterior of the bottle is super hot from being in the sun, the water inside is still cool. I’m buying more for backups and some even for friends!!

Ice melted very quickly. I have other water bottles which hold ice for hours. In this pair, the ice did not last long at all. Pretty disappointed. I gave this product 2 stars because the bottles had good caps on them which stayed closed and were easy to use.

So I kept these for over a year before writing the review. They’re great. They keep water and drinks cold all day and sometimes to the next day. If you put ice in it too the ice is still there too! The cap is simple which I love so it’s easy to clean and there’s no little spots for me to imagine gross things growing. I call it a win win.

My drink remained cold for over 12 hours. I am completely satisfied with my purchase.

I love that these insulated water bottles have a push button flip top.

Great Value, keeps cold, and love the lid/mouth mechanisms !! Easy to clean !!

Gave these as a gift. My sister loved them. Zulu makes high quality water bottles.

These cups keep stuff cold all day and they are tough enough for our 7 year old.
