Great Warranty Service
Purchased this unit in 2013 and have had zero issues with it for almost 5 years! A week before it's 5 year warranty was up, had a couple caps failed, sent in the panel for warranty repair and couldn't be happier with the service i received. Chris at American Rotary was great. No questions asked just sent a brand new upgraded panel at no cost (including shipping), Here's a company that stands behind their product 100%. A+++ product and service Customer for life.
