Review on 🍺 Beer Buddy Insulated Can Holder - Vacuum-Sealed Stainless Steel - Beer Bottle Insulator for Cold Beverages - Thermos Beer Cooler - Fits Any Size Drink - One Size Fits All (Matte Black) by Cathy Donaldson

Good product but I returned it to a competitor due to the fit of Guinness bottles and cans. Guinness bottles and glasses are not standard and I bought these and the others to see which would suit them best. The competition fitted a little higher on the can and bottle of Guinness and was a little tighter. Even if you drink Guinness, this is a very good product for you. I just chose a different one based on something most people wouldn't even think of. PS I was just looking at some of the negative reviews with pics of the top just sitting on top of the beer bottles without trying to lower them. These guys need to go to the gym or something. All you have to do is place the jar or bottle, press the lid and twist. The bottle or jar may rotate with the lid, but it will work. Push harder if you must. It will also expand over time. Crazy.
