Query: Absurd design. It's like leasing a rice cooker with a large downpayment.

As others have said, the design of this and other Sanyo rice cooker models requires that 1. its clock be running, and 2. its clock-sustaining battery be replaced each 4 to 5 years, which entails dismantling the cooker, de-soldering the old battery and soldering in a new battery.So if you want to use this cooker for more than its first 4 to 5 years, unless you are handy with an electronics soldering iron (and have the right type for working with circuit boards) and are able to dismantle the cooker (I tried and could not do it), you will have to pay again some 30% of the cooker's original price each time its battery dies.Essentially, this line of Sanyo rice cookers (this model and similar ones) are for most people disposable: you may as well buy a new one when its battery dies.There will be no more Sanyo products for me.
