If you’re looking for a great alternative to glass cups because you have kids and they always break, then look no further, these steel cups work great! You don’t have to worry about dropping them, and they are just as good as glass cups for any type of drink. I think the steel does a better job in keeping the drink insulated. What I used to not like about metal cups in general is that they leave a metal taste, but for these, it doesn’t have a metal taste to it probably because it is electropolished on the inside. Awesome cups and made to last!
