A Rick Potvin Forum | Does Zmax Work?

I just watched the ZMax informercial (Feb 10, 2000) but could not find any independent reviews of the product on the internet. This forum is for discussion of the pros and cons, if there are any, of using ZMax. [As of 2010, we'll widen out to fuel saving devices as well]

[Federal Trade Commission case against Zmax](this case is still being pursued by the FTC but has not been resolved).

Editor Note-- This was my first "successful" forum in that it attracted wider attention on the internet and established my hobby career as a forum moderator for the decade ahead.
