Love the bottle shape, colour and design. Bought this product to keep my milk cool in my bag at work after buying a different brand that doesn't keep it cool all day. After seeing the claims regarding this product decided to give it a go. I have to say sorry guys, but it doesn't keep my milk ice cold like you claim. I never expected it to be freezing cold for 24 hours, but 8 hours would be great! Maybe I'm being unfair as I do work in quite a warm environment (an operating theatre dept) but I was looking for something that would perform. Still love the bottle though.
