Thanks for the test... going to get one for my SJ8 camera!
good deal, it actually works fairly well, this ride out to windy point was about a extreme of a test as I could find - very high gusting winds out there that day - here is a video of the ride I took up to the tram right before I did that test and I was also using the windslayer foam - only wind in this was from the speed I was driving - check it out, it really cuts the wind noise down to where it isnt bothersome at all
