I would also be cautious of this product.
Look at the warranty.
ELECTRICAL ITEMS: For warranty to be valid you must provide the paperwork and receipt of the certified dealer/repair shop which installed the unit.
Warranty does not cover install by customer or un-certified technician. Please be prepared to provide this information when contacting us regarding a warranty issue. If you aren't aware of how to use this item PLEASE research before purchasing to be sure this is what you need.
When was the last time Fantastic asked you who, when, where and what degree the installer had?
"LOVE and LOSS, are two of the greatest emotions one can experience. -- I went to school to learn about "WHAT GOES UP MUST COME DOWN" but I had to live my life to learn the lesson of: 'WITH LOVE THERE WILL BE SORROW'."
