These servos are awesome. I was a little hesitant on these as I had never heard of them before, and its not one of the "name brands" most of us consider. I did some research, and they have been a top company in Japan for a while. So I decided to give them a shot, and wow... I could not be happier. The authority and response these provide is top notch. I would put these servos up against name brand ones that cost 2X as much. I have these currently in a Goblin 630 Competition, and I am so glad i gave them a chance!!)
