Mi Zojirushi/Micom rice cooker is good, but the battery is essentially not user-replacable. I just set the clock any time I'm going to use the timer; it's a real letdown in something that otherwise has lasted me over a decade.
I own all of these things, but after watching repair guides for my specific model, I decided that it was a better choice to have a definitely working rice cooker that needs the clock set when I want to use the timer (I only use the timer maybe once a month). I agree about the repair thing in general though; I own trackballs; the buttons are almost always the first thing to wear out and they are very replaceable with an iron.
