what do people think of the only toddler cup that lights up?

"This is a great little invention. I bought it for my daughter when she was about one and she stopped waking me up at night to ask for water. She can see it in the dark and drink while laying down, no spills whatsoever. She is now 2 and I am using the second light refill. I have ordered another one for my new baby!)"


"brought this cup as the step before a normal cup for my little boy. he wasnt to sure of how to drink out of it but 10 minutes later after about 3 tries he had mastered it. it is completely spill proof and hasnt even cracked when he has dropped it. this cup is honestly amazing."
