Any Ideas for a fictional product to sell?

I'm writing a radio ad for speech for a fictional product. I need to have emotional appeal and maybe something to compare it too to make that product seem better with statistics. Also it has to be a one person voice because I'll be presenting it live. Any ideas?
if you can please include how you would use emotional appeal in a radio ad because I'm really confused on there part.
