Query: Nostalgia Pop Corn Popper is a big disappointment

Our church purchased the Nostalgia Pop Corn Popper and have been very disappointed. It will pop only a few kernals of corn and then stop popping. I have tried to contact the Helman Group who manufacture it and have had no response from them after two phone calls, three e-mails and two letters. I can not recommend this product to anyone on the basis of my experience.
