Query: Waste of money

My son had to earn this toy as a reward. What a disappointment! He was crushed when the icee machine didn't work at all. We cranked and cranked for 3 times the instructed amount and nothing. We cleaned the machine and tried again the next night with Dad reading the instructions. No luck. We returned this toy back to the store, but the kids were heartbroken that their reward was a bust!
