Why should I steer clear of cheap Fluidampr/Streetdampr imitations?

Don't be fooled by a product that looks like Fluidampr or Streetdampr and is even advertised as "Fluid Damper." The bottom line is this product is a cheap imitation. These imitations are not manufactured to Fluidampr's exacting tolerances and are not backed by Fluidampr's exclusive money back guarantee. Vibratech's evaluation of these viscous damper imitations has shown an inadequate fluid fill, making imitations less than effective at controlling crankshaft vibration. They are inappropriately packaged, which could cause damage in transit and rusting. Genuine Fluidampr and Streetdampr brands are always advertised with a registered trademark or the well-known logos, and are stamped with the brand name on the outer diameter of the product and on the packaging.
