It seems to me that the Hiclone device has recently graduated to TV advertising, I'm wondering if there may be any members who have actually tried one out and tested it?

I first saw one at a motor show (I think it was Melbourne) many years ago and it was sitting on a single strommie (BXUV of some sort, Ford from memory - but it would have fit on to loads of cars at the time). At that time it was a very simple vortex creating type device that sat on the top of your single strommie. You could almost make one from a beer can, but I never bothered.

The claimed fuel economy increase was worth a thought for the then 25 bucks (I think) it was goin for, but I never bought one.

It seems a bit more expensive now, I wonder if it works.

Anyone know anything about it?
