I discovered that these tumblers don't work well for children. They are too flexible. Kids squeeze them and the liquid splashes out. The covers help a little but don't really stay on securely. For my own use they are fine for both hot and cold drinks. No condensation on the outside. Dishwasher safe. (I haven't tried them on the BBQ grill yet, as your advertising says, LOL!)
