I used to use plastic water bottle. Until I accidentally dropped it on the floor and plastic broke then water leaks. So I tried metal bottles and realized I do like my water to stay cold. Have not tried with anything warm or hot yet. This water bottle has a nice little opening to drink from that hasn't given me any troubles, and if I get sick of the size of the mouth hole and want to drink water via straw instead, it has a different lid that I can put on without leaking problems. I'm expecting this to last me years. And notice that it’s hand wash only.
