Mr. Potlight is excellent and I will rank them as one of the most professional contractors. John and his crew of 5 men were very professional, clean and efficient. John provided great advice and he also followed up with proper inspection. We installed 40+ potlights in our house. (including main floor, upstairs and exterior of the house). I will definitely recommend Mr. Potlight to friends/relatives and use them again in the future. Great job!
