This was a very fun activity for summer with my preschool-aged boys. The net cage is high quality. The instructions are clear and easy to follow. We ended up adding on an extra cup of caterpillars at a discounted price and 10 out of 10 are now butterflies. I could not be happier with the experience!!! (Side note: while there is an included voucher for the caterpillars, you will have to pay a $7.95 shipping fee. Not a big deal, but I was not expecting that when I placed the order.)
