3,000 kms powering Bike-to-Bike radio in cold rain and blazing heat - dry, wet, day, night - robust, worked perfectly! - just watch out for "user error"... when inserting into an R1150GSA beak DIN power socket, make sure that you get it in absolutely straight - otherwise it can short out and blow that 15A fuse...no clock or ECU! but a GREAT PRODUCT!
