Thanks. I actually stumbled accross this thread a few days ago. Was my first time on the UKGS forum. Seems like some decent info, as here, with a milder "attitude". Both good sources of info.
I have email Jens (manufacturer of the Booster Plug) and placed myself on the waiting list.
After I get it, I will post my feedback on Advrider, but likely won't be until March, as winter has set in hard in my part of Germany.
