We had no ceiling lights in our Living Room, and always had to make do with various lamps, leaving us with numerous shady areas. My wife saw Mr. Potlight's product at a friends place, and on their recommendation, we had them in. What a GREAT improvement! The room is bright and well lit, no shadowy areas.
The work was done quickly, professionally, and NEATLY (ie cleanly) by Peter and his assistant. As an example, they had extensions on their drills to capture drywall dust. They made sure to sweep up and tidy up as they went along. And they minimized the holes needed to run wires and connect to the switch.
I wholeheartedly recommend these guys and their product to you, and just wish we'd had them in sooner.
