Bests & Worsts Reviews from Amazon

I was very disappointed with this product. Partly it was my fault because I jumped to the conclusion that it was a doubled wall container. From experience I know that double walled containers are very good insulators. When I put a beer bottle in this insulated bottle I could feel the cold reach the exterior immediately. I guess most people drink their beer very quickly, but I was hoping for something in which I could take my beer and have it ready to drink an hour or two later, something that could easily happen with a double walled container. More importantly, when you place a glass bottle inside your product and then put on the stainless steel top, the beer bottle is pushed down to a position that makes it impossible to drink. In order to drink you would have to unscrew the bottom and push the bottle up again. Very awkward. Maybe if the screw top were longer (deeper?) more bottle top would be exposed when it was unscrewed. That modification and having a double walled container would make this an excellent product. I will be returning the product.
