It is hard for me to rate this product, as I have nothing similar to compare it to, and it was the only one I could find. However it is very simple to assemble and install, and there really isn't anything to go wrong. I have it connected to my emergency 10 hp kicker, on my 21 foot cabin cruiser, so that I can operate the kicker from the helm station, and it operates just fine. My only complaint with the product is the finish on the plastic knobs on the throttle and gear shift levers. There is a very sharp seam around the circumference of the knobs, from the mold. Not a deal breaker, but I had to file the seams smooth, or risk a minor cut during use.
