well just about everything! the litecup has been redesigned, we have a spanking new website and we are looking to expand to our range (more about that soon!). for existing litecup lovers - rest assured nothing fundamental has changed but hopefully you'll love the tweaks. for newbies please explore our site and find out more about the only sippy cup that lights up! Please check out our site and if you have any feedback on the product or site functionality we'd love to hear from you.
