I am still using my late mother-in-laws hand mixer, I have no idea how old it is but it is either made of metal and bakelite or some very old hard plastic, and the model is a sunbeam mixmaster junior. It works far better than any other mixer I have tried, in fact I have just given away a food processor because it isn't as good. My mother-in-law would have been delighted and amazed that it mixed my husbands 60th birthday cake last month, and it is showing no sign of giving up.
