Recieved the fans for my 509 goggles, nice little unit fits perfect in the goggles. rode all day yesterday. Have to say it works really well ! left it on "auto" and it switched on and off very well.
I would recomend the unit. Hope it holds up all year. It would be nice to have a "super high" switch for a bit more air flow when sitting still and leaving the goggles on, but still all in all works very well.
