KPIC 14 oz. Can (6-in-1) (Silver) Tumbler & Can Cooler (Use as 14 oz. Tumbler & Fits 12 oz. Cans, Slim Cans, 16 oz. Cans, Alum Bottles, 12 oz. Glass Bottles)

I can't tell how much colder it keeps things, but definitely prevents condensation and makes for a good uniform size for cup holders. I like those slim can energy drinks in the morning on the way to work, but they turn over and flop around in the cup holder spilling in traffic. The KPIC holds the cans and fits perfectly in my cup holders. So, no spilling. All the cans I've tried up to 16oz. And standard glass bottles work great. Odd sized or shaped bottles don't thou.

This is a great product if you are going to use it as is. I customize tumblers so the raised kpic logo and the weird octogon shaped bottom is very annoying. There's a rubber piece on the bottom so you have to tape that off before customizing it. Just a lot of extra work for what i have used them for. But...it does fit every 12 oz can or bottle that i have ever tried. 5 stars for the product. 3 stars for customizing.

The product definitely works as advertised. I like this because it does fit multiple kinds of cans and bottles pretty well. Just don't expect everything to fit perfectly. It is a 6 in 1 product. Very worth the money

Love it
