Does not keep ice from melting as long as they say it does. Only last maybe a day if that. Most the time just a few hours.

Nice concept, but would work much better if you could freeze this bottle cover. (tried it & not gel, because will not conform to bottle shape. It will keep your drink cold for maybe 15 minutes in the house..outside about 5 minutes here in Fl. Would not buy again. Has to be something better out there to keep your soda bottles cold longer.

There is no insulation so the ice slowly starts to melt if you don't use it right away.

For the amount of money I spent on this product I was hoping the cooler portion would actually keep things cold. I used a full sheet ice pack and nothing stayed cold. The ice pack melted faster in the cooler then in a traditional backpack.

As a way to track water consumption it's great, however it doesn't stay very cold and with having to add in a lot of ice, it throws off the actual amount drank if the ice isn't melted.

These ice trays work well enough, but the ice doesn't come out easily.

Obviously very safe for animals and walkways - just not particularly good at melting ice.  Does not compare to rock salt or other non-salt products

The ice cube trays work well but they don't stack on each other which makes the water spill out and freezes unevenly unless you put them directly on the freezer rack instead of sticking them on each other.

I thought this would be comparable to a yeti. While it did keep water cold, the ice I put inside the cup melted within 10 minutes in my air conditioned car. I expected the ice to last awhile longer.

While these are extremely hard to find, they are worth the trouble. They will retain ice overnight and keep your drink cold for close to twelve hours and cost a fraction of a Yeti. If you can find one jump on it.

They simply don't work for me.  Love the idea of not having ice melt, but they just don't cool as fast or efficient as ice.  If you are looking for something to make your drink slightly cooler than room temperature, they work fine.  If you want your drink cold, these are not it.

It's not like the premium brands, my Aunt has a different brand then I have and her ice doesn't melt like 6 hours, mine is melted in about half that time

The bottles do not keep ice frozen longer than a few hours...  but the bottles do not leave condensation on the outside... do that's a good thing.  But don't expect ice cold water after a few hours....

I really don't know if these truly melt slower, they tend to crack in half. But they sure are a cool ice cube. Will try distilled water, maybe my filtered water isn't pure enough.

HARD TO GET ICE OUT OF. THEY ARE MADE OF A SOFT RUBBER AND THE ICE STICKS TO THE SIDES

We bought these for use in our RV instead of constantly filling ice cube trays or buying ice. They work great at keeping drinks cool, but not so great at cooling down hot drinks. Having the tongs are nice, but we took took them out of the case and put them in a drawer, as ice cold tongs aren't much fun to use.

I ordered these for my dad.  He likes the color, size, etc., but they don't do what I ordered them for...keep drinks cold.  He even put just ice cubes in, 4 hours later he had just water.  That would work with any glass.  They don't seem to be very insulated.
