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.

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.

I really love these water bottles we put ice water in them and it will remain COLD all day long. I’ve forgotten my water bottle in the car on blazing hot days and when I get it at the end of a very long day there is still ice in it. I would love to give it 5 stars but…What I don’t appreciate is that the rubber ring on the lids snapped - wish there was a better system for this.

We purchased a 2 pack at Sams, looked like a nice easy to handle bottle for drinks away from home. After about 3 days of use on a trip, both of ours had the plastic part on top break, one leaked all over the car. I found the warranty website, lets see if they replace them. I would like to come back later and report they replaced them and now they work well, we will see.

These are the best water bottles we have ever used. I am a teacher and I take one to school everyday.I have had ice last over 12 hours even after the drink is gone. They lock so the lid does not pop open by accident. The spout is big enough for a big gulp for hubby and a small sip for me. The opening is large enough to wash well and I even put in the dishwasher. You will be glad you bought them.

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!!

Lid broke, and the rubber has a really bad smell! Now my trashcan has that smell!!

I bought five of these in September, 2021. The lids to all but one have broken.

Bought the 2 pack. First lid wouldn't tighten within a week. Second one lasted a couple months. Now both are useless.
