No Spill Lite Cup - Replacement Light Units 5 "Tried and Tested by 2 yr Old!" Mrs Amanda Mitchell 18 February 2008 Wow! Thought I'd buy this product for me but my two year old daughter is now proud owner. You can actually lie down and drink from this cup - its amazing! Its safe too as the base has a light in -(which can be deactivated if you dont want the light on) and it can also be completetly removed. The glow is just right and its a real mystery as to how it works so well!
