Following on from the "Vortex" thread, I wondered what other memorable devices are available out there. Let's see if we can't come up with a list, the criteria should be
1) Completely useless device
2) Outrageous claims for performance/efficiency/Manhood increase/whatever
3) Ugliness
So, any ideas? Personally I'm rather fond of the slick on fuel filler cap cover plates that are supposed to look like a flip-off F1 style cap (only these ones are made of sticky back plastic)
Cheers,
Jason
