My initial impression of this controller was good. Its a good pocket size, feels good in your hand, and very reliable. The one downside to this controller is the feel of the trigger. The trigger opening seems too small for what I'm used to on my HK-GT2B. Decided to see if I could remedy this problem. Took the controller apart and removed the trigger from the pot. Then took my heat gun and carefully heated the trigger arm that does the braking until softened and bend arm increasing opening. Its a simple mod that gives the same trigger feel as the GT2B. While you're at it, you can reposition the strap from the battery lid to the corner case mounting position.
