This part looks good, the sound is the changeable throttle in a chainsaw well again! The "chain" is on top of the Sword visible (=> beautiful appearance), but hidden below (=> low risk of any damage), so thought out for children's hands, no matter big or small ... Cons: battery compartment just me screwdriver Open: Batteries should be included allegedly - there were not. Are indeed only 3 AA, but still ... why only 4 out of 5!
