What are the care and cleaning instructions for the GoCup? The GoCup is dishwasher safe (top rack only).
Are there any differences between the 4 fl. oz. and 8 fl. oz. GoCups other than the size? Yes. The 8 fl. oz. also has a "DoubleDecker" tray that gives you the option of two smaller chambers (to organize pills, for example), or one large chamber. The "DoubleDecker" also creates a handy portable pill box you can take on-the-go by itself.
What units of measurement are marked on the GoCups? Both sizes of GoCup are marked for "cups" and "ml." The 8. fl. oz. size goes up to 1 cup and 200 ml, while the 4 fl. oz. size goes up to 1/2 a cup and 100 ml. The 4 fl. oz. size also has markings for 1 and 2 shots.
Can I use the GoCup for a hot beverage? The silicone of the GoCup can hold a hot beverage; however, you may find that the silicone is too hot to hold around the middle -- you may only be able to hold it from the bottom or the upper lip if you put a hot beverage in it.
