Query: Blaster Doesn't Work

I purchased two of these for my son for Christmas, and I am very disappointed. The company claims the blaster works with store-bought marshmallows. It doesn't. So I purchased the "specially" formulated marshmallows for $10 including shipping from the company. That was nearly two weeks ago. So far I have received nothing. Even though I've emailed the company asking where the purchase is, they have not responded. Don't waste your money - poor product, poorer service.
