Bests & Worsts Reviews from Amazon

First, I want to acknowledge a lot of the frustrations that have been posted about this product, and yes I am familiar with the old Stanley thermoses, but I honestly believe this does hold up when used properly. In the old Stanley models you never had to warm them up, at least from watching my dad, grandpa, and great-grandpa fill theirs up. On this model however you do have to put your tap water on high heat and fill it then put the cap on and let it sit for 5 minutes. I have noticed when I don't do the 5 minute warm up my drink does become cold, but when I give it the 5 minute warm up I get that good ol' 500 degree tongue burning 7 hours later on the fishing boat. I give it 5 stars because the instruction clearly read put hot tap water in there and put the cap on and let it rest for 5 minutes, so by following the instructions it does exactly what it is supposed to do. Now, if you just insist on pouring your drinks and soups in there all willy-nilly style because that's what you're used to then I am sorry to say but you're heading towards disappointment. I hope this helps everybody
