“On the plus side, the tumblers don't break when dropped. On the negative side, they're heavier than plastic glasses and one can't tell how much liquid is in them by weight. Also, they sweat a lot, and don't keep drinks cool as long as double plastic tumblers. Finally, they tend to spill over when the top is put on, due to the air tight fit of the straw.”
“Like the size of these tumblers. You need slightly larger to allow room for the lid. You can’t really tell from a phone picture but these lids come with a wider holed straw than the other lids. Just something to know if you either really like or really don’t like that size of straw for drinking. They also don’t currently sell replacement straws in this size although other hard plastic straws will work in the lid. Love all silipint items!”
