I've had this water bottle 4+ years and it is a TANK. I have filled it with water, pop, tea annd coffee and it still works beautifully. (Though I do recommend only water so you don't have to worry about mold) I have dropped this thing so many times and though it's dented and heavily scratched there is no rust or damage to the inside of the bottle. It keeps water cool and tasting fresh all day, especially if you have ice. I also left it sit out for a year with water in it and (thankfully) there was no mold inside and the water looked fresh as the day I put it in. Even the plastic straw and o-ring were perfectly fine.

I, like most, have a hard time drinking more water than beer but I can genuinely say that this is the best size. Its not this giant gallon size water bottle that can look overwhelming on your desk. It is durable and the handle feels sturdy so I feel comfortable walking around with it or throwing it in a bag. My favorite part is that it has helped me a lot with drinking water. I fill it up when I get to work in the morning and again at lunch so by the time I leave I have had 80oz of water. Highly highly recommend this size water bottle and getting the little no slip grip.

I really like the extra space in my 40 ounce bottle, which my wife brought home yesterday. I always fill my bottles with water and ice at night so I have ice cold water for my morning workouts and this fit the bill very well. My only problems are, as others have said, it does not fit into a cup holder in the car, and it doesn't fit under the ice maker, so I have to dump the ice from another glass into this one manually. Still a keeper, though.

I’ve been using it everyday over the summer for work and it keeps my water cold. Surprisingly enough I hardly put ice in it. Just cold water from the fridge and it keeps it cold all day. Would love to see a bigger option cause there are some days I run out of water.

I bought a 24 oz flask, but never opened it or used it until about a month ago. Now it's in use every day! Need to keep hydrated for health!! Very convenient to use. It does keep cold liquid cold and hot liquid hot! I like both lids. The flask looks great! Am ordering a larger one today. Highly recommend!

Unfortunately, my 24 oz tervis cup does a better job keeping my water cold. I filled the thermoflask with ice and water the night before I went to bed and put it in the fridge for an early morning workout as not to wake my husband with the ice dispenser. The ice was totally melted when I took it out of the fridge the next morning. I did the same routine with my Tervis cup and it still had ice in it when I took it out of the fridge. Even during the day, I notice my ice will melt pretty quickly while I am in my house. My husband has 2 of these. One works well and the other doesnt.

This is a really nice product. Really well made and think. The 2 different lids are very practical. The one with the straw can be opened only by one hand, which is fantastic for drivers. But I love the other one more for the day to day in public transports. The hole is just the right size, and the grip are perfect. I appreciate the fact that the company is a good one, cause the sell all accessories to. So if something happen, I will be able to "repair" the bottle. Instead of trashing it. I hate to polute the planet for nothing. So I'm in love with every aspect of the product. I wish to the company the best.

Solid drink holder, keeps my iced coffee very cold, but as others have reported, some air leaks into the straw even though I have checked to make sure the straw is fully open

The size is great! It's perfect to have at my office and it keeps my water cold all day long. I have ice for days!! I really recommend this water bottle. I also have a smaller one and it's just as wonderful. You will not be disappointed.

It is an excellent product as other sizes of your bottles, it would be good that this one has a protective silicone bumper too.
