I have not heard of that brand before. I have two VCM Tuner II installed and they install in minutes, then never touch them again. Other may be making a device that will work and is cheaper but if is not done properly the savings may not cover the damage. I have not heard of any failures on any of the other brands so I can’t tell you what to watch for.Anyone have any experience with using the "AST Smart ECO VCM Modules" from Aperture Science + Technology? There is a single resistance model and a variable resistance model.
