The Mr. Potlight crew was efficient and thorough in installing potlights in my living room and kitchen. They checked the bathroom upstairs to ensure that they wouldn't accidently hit a pipe when installing the potlights in the ceiling. They added a dimmer switch for us and they told us where we could buy the LED lightbulbs they used. It's been 3 years since installation and we are still happy with the job they did. And they were right---we haven't had to replace any of the lights yet.
