Tumbler Buddy Instant Chilling Cup – Keeps Coffee, Iced Coffee, and Cold Brew Refreshingly Cold – Freezer-Ready Cup for Quick Chill, Perfect for Hot Days – Reusable Stainless Steel

These work great at turning your Yeti cup into a drink coozie!

First of all, this product is a stainless steel insert and a silicone lid ring for a 20oz tumbler. It does NOT include a tumbler. Although, if you think you can get a Yeti tumbler and this product for under $10, I want whatever you’re smoking! This product is fantastic. You put the insert in the freezer and when your ready, you just pop it in your tumbler (works great with my Yeti or Ozark Trail (Walmart) 20oz tumblers), add your favorite beverage, and then put the lid/ring on to keep it in place. It fits my 12oz coke cans, beer bottles, and seltzers (slim cans). I haven’t tried it on a 20oz soda bottle yet, but it would probably work. You can also use just the insert as an unmeltable ice cube to keep your bourbon cold and from getting watered down. I love that I no longer have to decide what drinks I have to pack in my backpack (to-go) cooler because of which koozie I bring with me. This gives you all the options and even takes up less space. I just bought a bunch more for gifts.

This is such incredibly deceptive advertising. The whole presentation makes it appear that it's a tumbler, out similar to a yeti cooler.I received a plastic ring and a small metal base.All this does is increase the energy footprint behind stupid products requiring returns.

I had to return mine because every tumbler I owned wasn't compatible. I must not have read the description in detail. I ended up buying or rather getting a free sample of a Koozie brand tumbler that came with the option of using different sized beverages.

The description is spot on. It works well with my 20oz Yeti tumbler. The insert helps keep drinks cold, after chilling it in the freezer. I like the fact that I don’t need a bunch of different cozies for all different types of drinks.

Loved that this makes my Yeti cooler able to hold various sized cans, in addition to just liquids. Keeps my beverages cold all day and is easy to use. My only complaint is that the fluid in the stainless insert makes it so that the cup is so heavy that it's difficult to know when your drink is low or gone. Otherwise, great little invention.

The product was so easy to use. Just place the stainless piece in the freezer for a couple of hours, then in the bottom of your 20oz tumbler. Good for brew after brew.

Convenient, versatile, well made. I use it every day. I especially love it while golfing
