I like these bottles, they are good for keeping cold cold and hot hot. I do know that they make them with steel tops, like, the indside that goes inside of the bottle and touches your contents but this one is plastic. I can likely buy a different top and replace it as I believe they are all the same size. I have had this brand before, both with no company name and also I believe these are the same brand food babe was selling but I know that I had ordered some with the upgraded cap. I am all freaky about plastic LOL. Some dirty genes making me paranoid?? ;)
I also wish it wasn't hand wash because .. Lazy. I will blame the genes!! :) The ones I can't clean!! But it's a great size, and I love that I will be able to carry with me healthier choices and keep them the temp that I choose.
