OXO Tot Transitions Straw Cup, 9 oz - Navy

OXO has always made good products and so these can't be too bad off first glance. We have tried many types and brands of bottles, but many factors place this bottle as our top choice eliminating other bottles from daily use. 1. These bottles and all of the parts (4 total) are easy to clean...by hand or dishwasher. 2. These bottle tops are compatible with their smaller siblings at 6 ozs. So if you decide to start small and decide to upgrade, you arent losing much functionality since the straw mouth piece and in-bottle straw and re-usable. 3. These are pretty much spill proof.....*with exception of the child sipping and leaving behind some liquid beyond the rubber stopping point (1/2 extended into top rubber mouth piece). Compared to others this is great. 4. Nice simple design without much fuss or assembly issues.
