The Funtainer Straw Bottle by Thermos comes in 28 different designs, including numerous character themes, such as Shrek and Dora the Explorer. The Funtainer is dishwasher-safe, although the manufacturer suggests hand-washing for best results. However, some reviews state that hand-washing proves to be difficult because proper cleaning of the straw is challenging. There are few reports of leaks, and although some older reviews complain of the lid breaking off, this problem has been remedied in Funtainers made after 2009 with a reformulation of the plastic used. Like the Playtex Insulator Cup (*Est. $5), the Funtainer has double-wall insulation to keep beverages cold and a condensation-resistant outer shell. The Funtainer and other straw cups are not said to contribute to tooth decay because they direct liquid to the back of the mouth. The Funtainer should not be used with carbonated beverages, which will cause leaking, or with hot liquids.
