Product review (1 stars): If you believe this, I have a bridge I'll sell you
This item is a con job, akin to those fuel line magnets and carburetor water injectors back in the 80s that were supposed to increase gas mileage.

The main difference is that the sellers here are audacious enough to tack on a price tag of almost $100. What is the logic of this?

Buyer's perspective: If the device costs this much, it almost HAS TO WORK.

Seller's perspective: If I bump the price by a factor of 10, I only have to find 1/10th the number of suckers.

Please consider the old adage:  It's too good to be true, it probably isn't.
