After going through a new toaster oven every couple of months - none of them lasted longer than a year - we decided to end this ridiculous "buying and throwing away  cheap toaster oven ritual" by getting a topof the line DeLonghi.  It worked just fabulously, and we could not rave enough about it - until this morning after about two months - when DeLonghi suddenly lost some vital parts during breakfast preparation.  That was not a good way to start the day. I called the DeLonghi service line to find out what to do with the diseased member of their family, while staring at my uncooked bacon.  I punched my way through a maze of useless automated telephone response options - finally after half an hour on the line,  I got a rather unfriendly and unresponsive customer service agent who advised me to contact the nearest service center, which is 27 miles from home (one way).  This meant driving 54 miles to bring the thing there and 54 miles to pick it up - or two half day excursions to the Los Angeles area, braving L.A. traffic. After learning that it would take between four and six weeks to fix my DeLonghi  (there must be a lot of DeLonghis giving up the ghost prematurely),  I called Amazon to the rescue.  My concerns were handled professionally and  responsively by a friendly AMAZON customer agent (the DeLonghis could learn from them). AMAZON is sending  a prepaid UPS return label and the DeLonghi goes back where it came from - full refund minus restocking charges - much better than wasting two half days in traffic.  Impressed and reassured by this AMAZON performance,I ordered a new one as our family cannot live without a toaster oven.  However DeLonghi is passe, so we're going with a Cuisinart with a standard 3 year warranty. Thank you AMAZON, you are a great dot-com !
