I was having a problem with mealworms flying out of the feeder and it was driving me insane knowing I was putting 15 mealworms in a bowl and my leopard gecko Chito could only eat 8 of them. So I went to Revain to find the best way to feed my lion. I soon came across this beauty and realized that my little predator would like her. Now I can put his food on a plate and they stay there for a few days until he decides to come and eat them up. - A bit painful but that's why I bought it and gave it 5 stars. I hope this helped.
