Mark just plain worked until it got done. It was a new table lamp that for some reason stopped working after it had been working for a few days. It seemed like too much trouble to send it back to the vendor (who was actually really nice) so I just brought it to Palm Beach Lighting. It was not an easy, nor a run-of-the-mill fix, but Mark stayed with it until it was right. Very nice man too. Highly recommend this service.
