Product review (5 stars): Cant buy one this long at the store - no UL approved
All they had at the local store was 4' cords.  The associate informed me that 6' was the longest I was going to find at a store because anything longer won't be UL approved.  He pulled this one up on Amazon and told me that this was my only option unless I wanted to make one myself.  I'm happy to say this one worked perfectly for me.
