Free Tool for Testing Startup Ideas

Does the "like/tweet/pin us to even try our product" appeal to a large group of people I'm not aware of? My initial reaction to these tactics is a mix of "Gee they must not think they're product is very good" and, "Oh, fuck off."

It's asking for a personal endorsement (one of the most valuable currencies at my disposal in the information economy) of something I do not yet have the option evaluate. I was really excited to try this, but I'm not going to. Ick.

Do they have guarantee? If you aren't satisfied we will give you back your tweet all you pay is shipping and handling.
