I was shooting a night snowboard rail jamb last week and meet a guy using this set up and loves it. I did some research and he sent me this review. He has been using them for 8 months now without any issues. For 44.00 shipped from amazon I got one and so far it works excellent. I plan on giving it a good workout this weekend.
Probably not for the pro's on this board but for the hobby guy at 1/4 the cost of a Pocket Wizard it seems like a affordable alternavite. Just passing it along.
