One of my least important criterion for DRTV products is credibility. It was No. 7 on my Divine Seven checklist, and didn't even make my SciMark Seven or Fabulous Five checklists. That's because DRTV buyers often seem willing to believe anything if the problem/solution or "wow factor" is strong enough. But there are limits.
In my opinion, gas-saving products always have a significant credibility problem. This particular item is especially lacking in believability. The idea that you can plug something into your cigarette lighter and have it do anything beneficial for your car is ludicrous on its face.
These products also suffer from weak economics. That is, it's hard to justify spending $40-$50 (with shipping and upsells) to save pennies at the pump.
