Had the artisan kitchenaid mixer for about 4 years. No problems with it whatsoever. Great mixer also. Just decided to upgrade to a bigger one cause making desserts constantly and felt would prefer a bigger 6 quart one. Works great and easier to work with, since it is bigger and more room to work with.. 
P.S.  You will be very pleased it you buy the 6 quart kitchenaid mixer. 
Buy it up!!!! (This review was collected as part of a promotion.)
