how do i get the top off inorder to put the straw top on? i understand i have to screw it off but how do i detach it from bottle.

Before you use the straw lid with straw, you should take out the flex cap. The flex cap is held on by a plastic loop around the neck of the bottle. You can pull the loop to angle it and slide it right off. And you can take it out.

hey everyone, does this "sweat" with cold drinks?

Hello, Thanks for your question. All of our water bottles are made of double wall stainless steel, that will never sweat with cold drinks, thanks Please don't free to contact our customer service if any questions, we will do our best to help you, thanks Best Regards, BUZIO Customer Service

Is there a place or vendor that has extra lids?

I have just ordered from Amazon. The wide mouth is pretty much the same for all hydro. I have not ordered one that did not fit, some I like better then others.

Does the water smell when it's in the bottle for a day?

All stainless flask water bottles need to be cleaned often. Hot water rinse every day is basic. A little white vinegar in hot water is a better cleaner and best is a bleach water rinse. In the summer you will have to rinse the bottle more often. I have used a 64 oz Hydroflask for 10 years and you just have to remember to clean them. I replace the straw lid every 2 months or so. Also remember to clean the straw lid with the supplied brush under hot water. I recommend buying a flask cleaning brush to scrub the inside. Bacteria tends to build up at the bottom of the flask, around the cap seal and where the straw attaches to the cap.

Large and heavy duty

I love this water bottle. It’s larger than most I’ve come across, is excellent quality and heavy duty construction. It also keeps drinks cold for a very long time. Next best thing to my yetis.

أداء باهر في السنة الأولى، لكن العزل يضعف لاحقاً

ممتازة جداً واستمتعت بأدائها طوال سنة كاملة، لكن بعد هذه المدة بدأت تفقد البرودة بشكل ملحوظ ولا أعلم ما المشكلة.
