My answer would depend on what your warranty is on the replaced unit. My only problem (?) with the "extended " warranty was that it takes effect when purchased. New units have a one year warranty so what you are buying is actually only an extra year, not two years. Of course the square trade warranty also includes accidential coverage so that must be considered. If I had it to do again I would look at the option and availability of purchasing the SQ warranty after about eleven months from purchase of the unit.
