Purchased in fall of 2010. Have had major repairs and no, I didn't buy the long-term warranty.
My last Panasonic lasted 12 years with no repairs. Now this one has quit again. The original price for microwave/convection was over $600.00 and it has now cost approximately $900.00 --- this time will discard but don't think you should be in the business of making microwaves!! Purchased at County Alliances, Toronto --- they too have been useless in providing support.
I am the only one using the machine and use rarely, particularly since it never work beyond the first 12 months. No more LG appliances for me.
