In either case, if I had a dime for everyone who has pitched a "wonder product" to me I'd have a tidy sum. They usually turn out to be nothing special to write home about when you consider the myriad of other products available that are either comparable or better.
Ask him specifically why this stuff is better than others that are available. Usually when someone gets this excited about a product they typically have limited experience with others. ....that's not to say it's bad but just suggesting to keep things in perspective. I'll wager you'll get the "tried them all" claim when you ask.
