Ben W.wrote a review of DAKINE Adjustable Tuning Iron - USA on January 10, 2013
Overall this iron will get the job done and server as a nice replacement for whatever non wax approved iron you are using. It heats incredibly quickly to the temperature that you need to melt your wax. I generally stick just under 100F. I'd estimate it takes 10 seconds to get there. Backing it down to a lower temperature is just as fast surprisingly.
I'd say the only thing that I don't care for on this iron is that it scratches very easily. I already have scratches on it after a few uses from the base edge of the board. I would still highly recommend it as it pulls the wax evenly across your board.
