Tcamp Ice Cube Tray for Stanley Cup 30-40 oz Tumbler Cup Ice Mold, Silicone Ice Tray With Lid and Bin for Chilling Cocktails, Whiskey, Drinks, Coffee, Easy Fill and Release Ice Maker (Green)

Ice tray works great, the ice lasted all day in my cup.

Oklahoma has been like the surface of the sun these last few week. That’s why we bought these. We hand washed really good after delivery so we could put them in the freezer faster.The white film was so bad from the first ice that we dumped it out, washed the cup, and put the tray in the dishwasher.It still had a light film on the ice after the dishwasher but I was walking in lava and needed hydration. I drank it, it didn’t kill me.These take some cup space, so if you drink water like me (warehouse work in summer with no AC) you need a water dispenser close by so you can keep filling up your cup.Side note, I’ve gotten several brain freezes from drinking water with this ice in the cup, and the chilling part from the dispenser does not work so water going into the cup is semi warm.These last about half a day before melted in the described conditions.

THANKS TO WHOEVER THOUGHT OF THIS BECZ ITS KEEPING MY WATER COLD UPTO TWENTY HOURS AFTER I SET IT UP. I ALSO LIKE THAT THEY NESTLED IN THE TUMBLER JUST RIGHT. THANKS AGAIN.

These molds are cute, easy to fill and do fit the Stanleys as advertised. I've used them in other cups or jugs, too. But I just want everyone to know: the ice does NOT last that long. I can fill one Stanley with regular ice and another with these molds. At the end of the day, the regular ice will have more left than these melted down molds.I've also seen some where it's just the ring mold and it's not connected to the entire tray thing. My sister has some. Those are more easily stored, don't take up as much room and honestly easier to free the cubes when they're frozen.

We camp quite a bit and this provided ease and long lasting ice cubes for my drink cup. Used it many times and look forward to many more. Great purchase and price for item
