I needed someone experienced with light switches and wiring to help me figure out how to connect a porch light switch. The wires were in the wall, but I wasn't sure which ones they were. Someone had instead installed a pair of switches for a fan/overhead light. He figured it out, which was great. He even went to the hardware store and picked up a switch. However, it didn't match the color of the other switch next to it, and he didn't seem willing to go again and get one to match. Communication seemed to be the issue, not his knowledge. So, four stars for doing the most important part of the job I needed, but one star off because, for the amount I paid, I'd really have liked it if he'd realized they should match, gotten two switches of the same color, and hooked them up. I had to make two trips to the hardware store to get the right switches, a time consuming process.
