Query: Works great - for about six months

We've gone through two of these percolators in the past year. Each worked very well for a few months, and then problems with the heating element started. On the first unit, the element failed completely after six months, and on the second unit the failure was gradual and insidious. Our coffee gradually became weaker and cooler over a couple of months until one day I realized the pot was not heating the water properly.I note that the price is higher now that what we paid. Too many warranty claims Faberware?
