How long is your ice suppose to stay inside before it melts? I checked my thermos after only 6 hours &amp; all the ice had melted. I had put about 5-8 cubes inside before filling it with cold water.

It depends upon the outside temperature and the temperature of the water when you add the ice. The manufacturer says 18 hours and I have had it last that long in my air conditioned home. I have had it last 24+ hours in the fridge. But, in warmer settings, 6 -12 hours is more realistic. To maximize the time, start with a cool bottle (running cold water into it or even keeping it in the fridge). Then, use ice plus COLD water from the fridge (otherwise the warm water will melt the ice before the outside air gets a chance). Then, try to minimize time in direct sunlight. Using a room temperature bottle, plus cold water and only about 4 ice cubes, my bottle keeps at least some ice for the entire 10+ hours of my commute plus workday (desk work).

I think this is in part a function of the temperature of your freezer. However, we found that we had ice in only a few hours. I received my trays mid-morning. Washed, filled them and put them in the freezer. We enjoyed cocktails that evening. My husband loves them.

Ice cubes work great. I put in 4 or 5 and can keep adding water all day. I still have ice cubes in the evening. They never get in the was of drinking. This is a great product.

I've been using this product for months; it stays cold a long time after I use it. So if I put it right back in the freezer, it I think it only takes a couple of hours to freeze up again. Honestly though, I've never timed it because I bought 2 of them (1 to take to work). So if you put it right back when you're done, the time to refreeze is short.

I usually put ice cold water in at night and it stays pretty cold until morning. I'm not sure how long ice last depends on the area it's being kept. I use one at work as well and ice cold water is placed in it at 9am and last till I leave at 6pm still cold. Hope that helps

I put 4 bags of ice in mine and loaded it with beverages. 2 days later, yes 2 days later there was STILL ice in it!!!

We have an ice machine that makes small cubes. I use a small bucket, about 1 gallon I would guess, to fill the machine. It usually lasts about 4 hrs.

Hi Kathryn! There is an online eguide with instructions, but be sure that the purée is cooled before pouring it or putting the lid on (the steam can create the ice crystals), make sure it's not filled too full by smoothing over the top with a silicone spatula (overfilling won't allow the lid to close fully, and store in tray for no more than two weeks. Here's the link to the instructions guide from the manufacturer. http://www.mumiandbubi.co.nz/recipeguide.htmI've had great luck with my trays (& using these tricks!). Hope that helps!

put ice packs in mine. it is cold 9 to 10 hours later. If you preheat the thermos it will go just about 24 hours

I have haf mine for two or so years now and I cannot complain about the amount of time the ice melts. It will melt faster if in the sun, but we always mad ours when "ordered" lol the kids love to see the ice fall so that in itself was a treat... I am sorry, but as for an exact amount of time would be up to the weather conditions but agagin, I am very satisfied with mine! Hope this helps or you can get a better answer... :-D

The ice cubes fall into the storage bin and they melt very little because all the ice cubes create a "cold" temperature in the bin. Once the bin becomes full the ice maker stops making ice until the bin is emptied. I have been gone longer than six hours and the cubes still very large with minimal melting. The ice maker has great insulation to keep the temperature as cold as possible.

You will need something colder than just ice. The idea is to "freeze" it. Something that cannot be achieved with just a cooler with ice. After taking it out of the freezer it will last 30~40 min.

First, I would advise against it. Steel does not stretch the same way a plastic water bottle does. Second, and more importantly, because it is insulated it will take a l-o-n-g time to freeze solid, and once it does you won't be able to drink it... it will be frozen solid. If you FILL it with ice cubes before adding (cool) water, you will still have ice at the end of the day. I tend towards about 2/3 full of ice then filling with water and I still have some ice left the next morning. There is absolutely no need to try to freeze it solid, doing so will probably destroy your wonderful Kanteen, and should you succeed it won't melt fast enough to be able to enjoy the ice cold water.

The amount of water to ice doesn't necessarily matter. If you put more ice in, you can go longer before adding additional ice. I'm sure two trays would last several hours.

I had minds for almost a year now and it keeps my ice cubes for at-least 10 + plus hours, but I have notice if I put crushed ice it does not last as long as Ice cubes etc. But overall all it's been awesome for me, I suggest ask to get it replaced and see if the new one last longer etc. mahalo 808HI

Don't fill the ice too full. That may be it, but other than that, I am unsure. Hopefully it isn't defective.

Yes, I would recommend this for smoothies! I could not believe after 3 days I still had ice water in this thermos. To make the smoothies stay thicker longer, you may just want to put some ice in the thermos for 10-15 minutes to get it cold then remove the ice and put the smoothie in, should stay firm pretty long. These thermos' are great, best I've ever used and highly recommended for hot OR cold ;>) Enjoy your COLD smoothies ;>)
