lucy24 intresting observation but probably the reason is they were only made to last for two years. keeps you coming back for more. Ever wonder wwhy you buy a car battery with a 2 year warrenty and it goes bad at 2 years. Not 1 not 3 but 2. I think the companies are adding a self distruct device in them to keep you/me coming back.
