Review on 🥤 Large 8oz myColdCup Ice Sticks - Ideal for Wide Mouth Water Bottles, Beverage Dispensers, Water Jugs, Growlers - BPA-Free (Set of 4) by Pius Aponte

I have to say I poured cold milk (from the fridge) into my Manna Ranger (40oz) around 5:30am in the morning and poured about 4 or 5 ice packs. Around noon when I go to get some milk my brain can freeze if I drink it too quickly (much colder than straight from the fridge). When I get home around 4:00 p.m. there is still a lot of ice in the cold packs and the leftover milk is still damn cold. There is no "NO BPA” notice on the product packaging. Right now it's a psychological thing. Mar 27 '18 @ 12:20pm update I occasionally forgot to empty contents, clean/rinse reusable ice and bin. I get up in the morning (24 hours later) and find that my drink is still colder than when I poured it into the container the morning before. It's (I think) a combination of my manna and reusable ice. I'm bumping it up to 4 stars. I need to buy a backup set.
