Water Bottle Ice Stick, Reusable Ice Sticks for Water Bottles, Ice Pack for Bottles, Pack of 8, Colorful

I put them in my yeti cups and it never dilutes my tea. Like, ice cubes do! They keep my drink, cold most of the day!

I was looking for something to keep my pop in tall plastic bottles and these fit right in and once they are frozen they work really well!

These are perfect to use in cold drinks instead of regular ice that will make a drink watery. I needed some ice for a badly bruised finger. I wrapped one of these in a paper towel and it worked perfectly.

I am knocking them because I tried them.Many design flaws that I don't like.Before I go on, I will add and say, these aren't designed to *get* your drinks cold and stay that way. These are designed to *keep* your drinks cold and stay that way. As for both functions, I have to give negative points, and I could if I would. Reasons below.The "Flavor" feature rating Amazon is asking me to do is hilarious. This isn't supposed to have any flavor. It's plastic, and I did clean it with lemon-based non-toxic food-grade spray, and it leaves no aftertaste in my water. This is where I give a 5-star rating for that.But, as mentioned above, it does not function well as a drink chiller or drink chill keeper. Ice in it unfreezes in mere minutes, unlike a few other ones where I had it last nearly an hour or longer. I don't know if it's because the plastic used is designed in a way it releases cold temperatures too fast, but it sucks.And I had to knock off points for it being too narrow as well, which probably goes hand-in-hand with why it ends up releasing temperature too fast, as well. I'm putting it in my shaker bottle, and it pops right out of my cup and straight into my throat as I'm drinking water! Very annoying! But these are too long to fit in your regular water glass! Very annoying!The only reason I kept on 3 stars is because of its color choice options, and they're definitely pretty. And while I don't know 100%, the plastic used on this definitely feels non-toxic, which I could be wrong, but there's a lot of non-food grade plastic out there so I think that gives some options. These are probably great as an emergency ice pack in the right circumstances. I wouldn't buy these at the price rated now, of 10 dollars. I most likely wouldn't get these again.

These are great for water bottles—they just slide right in and back out when you need to clean them!

These reusable ice cubes are amazing. They change color when they are cold and turn white when defrosted. Perfect size for water bottle and drinking glasses.

They stay cold long enough to cool my water for drinking on the go, or cooling down a hot beverage to drinkable temperatures.
