I bought these as a stocking gift for my 5 and 7 year old nephews. They thought they were pretty cool! A bit pricey for what you get but in my opinion it's worth it because it's different and fun! This is definitely an improvement over the cheap plastic/paper versions! You might be looking at the Christmas tree lights or the neighborhood (street) lights. It works in any light, but you're looking at Christmas-themed images, so you can only use it once a year.
