I read the reviews before purchase and found most were honest and forthcoming. There was a couple that found the unpluging was a hastle and a couple more that discovered that you shouldn't set any appliance or tester, etc and the highest temp or voltage just for the reasons these people experienced which was inconvenience and burning. These folks were looking for something to complain about and if the instructions were followed they would have discovered that ALL small appliance that sit on a counter should be unplugged (by their own instruction books) and that setting the browning control at the lowest setting to start would certainly helped these individuals to be more satisfied with their purchase. I, for one, are most satisfied as the unit looks brand new and works as described. Would be most happy to recommend this product and also the LG microwave that I purchased (refurbished) two months ago. I plan on purchasing like products in the future.
