Over the years we have had all kinds of stainless steel contigo mugs. They cool my daughters water at school and are airtight. They still have ice in them at the end of the day. You can even add stickers to them to spice them up. I will say that these handles tend to break if your kid is rough. Some mugs have a handle that is built into the lid. By the end of the school year, the mug is usually dented, but that's to be expected. They are still usable. There are no problems with O-rings. Can be washed in the dishwasher.
