I was charged over 600 dollars just to change a GFI switch and put in a simple external outlet. They charged me 3.5 hours of labor x2 and one of the two men who came, drove back to Hilo for parts, which alone was an hour of the labor charged. I found this to be outrageous---plus it doesn't take two men to change a GFI switch. I would not recommend them due to their exaggeration of the actual work done and their dishonesty.
