Christmas present for my daughter. ease of use, but a little hard to rattle on the end so a young child (5-6) will not be force to play alone. My daughter is 8 and she understood TRSE operation. It is therefore easy to handle. She keeps badger. I am thrilled with this purchase. I bought a refill on and I think we will soon need. However, I read a misjudgment on refills and suddenly it worries me a little. We'll see.
