anybody bought one yet and does it make any difference to stability or m.p.g is it an expensive gimmick.

My thoughts entirelyLutz bang on, back in the eighties can't remember who did the appropriate tests, it was found not to improve fuel economy one bit, as you say Lutz where do you place it at the front, middle or to the rear of the car plus at the correct distance from the front of the caravan.
The only thing mine helped with back then was there were less flies on the front of the van, but a sponge and water were considerably cheaper.
Before l invest in one l would like to see the detailed test to prove it saved money on the incial outlay plus the pay back time.
