How ong will it keep drinks cold? or hot?

About 1-2 hours no ice, and around 4-6 hours with ice added for cold drinks in 80+ degrees heat with the top on the tumbler; half those numbers in length of time without the top on in my experience. Wouldn't recommend using this for hot beverages because I would be afraid that the plastic top would melt or warp and it would be difficult to drink something hot through a straw.

A long time. I can leave it in the hot car for an hour and I'll still have ice.

I only use this tumbler for cold drinks, once filled with some ice it stays cold for a couple of hours.

I'm not sure about cold, but it keeps liquids hot for at least 3 hours ( the time it takes us to ride to Vermont to visit relatives. I put tea in it and it's still hot when we get there.) The great thing about this mug is, when it's closed, you can toss it across the room and it won't spill a drop. Don't put anything carbonated in it. When you open it, it will gush all over the place. I hope this helps a little bit.

I think I keeps my water cold/ cool for several hours. Not ice cold but it does stay cool. It is quite large for Milk.

I personally use two little ice pack/bricks during the day. I do live in the tropical state if Qld on Australia so it's quite hot. Keeps cold for hours and hours. Great investment!

Sort of depends on what 'hot' is to you. I've had 3-4 hours of good temp. for my coffee with this thing. Does really well on keeping ice water icy as well!

Keeps beverages hot for at least 8 hours. And very warm for another 3 ...still very warm the next morning.

Hot??, that's subjective. If unopened it would keep hot liquid fairly warm. Best you can expect, subject to outside temperature

By "hot" I mean it is too hot to drink without burning my mouth (at first), and a few hours later it means too hot to drink without masochistic discomfort. Don't know about cold - haven't tried. WHOOPS! I thought you were asking about the Thermos bottle I purchased at about the same time. I have not been concerned about the bag's ability to keep items hot or cold. Sorry.

It keeps it cold and hot. And for the hot you have to put back and push a button and for the cold youkusthave to push your cup

I didn't try warm beverage. I tried it with cold water/juice and it holds cold temperature for hours.

It works great as a desk surface, it is rated to 300 or 400 degrees so hot drinks shouldn't be a problem

I only use mine for water, I think it would be fine for cold drinks of any kind, I don't think I would put any hot drinks in it.

It keeps both hot and cold...depending on what the temp was when place into the bottle. I don't think they recommend "hot" because since there IS a straw attached ...you might burn yourself. I put drink with ice in at 8am and left in car and carry all over and by 8pm, little chips of ice still inside. For hot, i don't put in boiling...i put in lukewarm and it stays lukewarm for quite a few hours as well. i don't think the plastic parts should melt since the straw parts are made of silicon. I also dip straw parts in boiling water to sterilize and it stays perfectly fine (I got the foogo for my daughter and her straw gets really nasty with backwashes...gross) hope this helps It keeps both hot and cold...depending on what the temp was when place into the bottle.

If you preheat the mug with hot water for a few minutes it will last up to 5 hours hot. If you put it in the freezer for a few minutes it will keep things cold for up to 7 hours as advertised. Be sure and use the open and close valve. This cup has a small bottom to accommodate cup holders in cars. It does tip over easily. I love mine.

It's decently insulated. It would keep food drinks cool for a couple hours without ice I'd think. We use cooler packs a lot which are nice because they don't melt

It's not meant for hot drinks. It's meant to be put in the freezer and used to keep drinks cold.
