i first purchased the SK550 model. in less than 3 uses it had to be returned for warranty repair/replacement. when they sent it back, guess what, they sent me the SK500 model.i didn't have problems with the unit initially - not even the bad smell that seems to impact a lot of people. however, just as soon as the warranty period is over - BOOM - the unit stopped working.i am a household of one - i used it only several times a week - not every day. so for it to go out on me in that short period of time is a waste. i liked it otherwise and it looked good. now i'm really debating if i should get another one. really have doubts though.
