I've had the red 6 cups Tatung Rice Cooker for 15+ years.  I've decided to gift it to my eldest when she leaves home (couple of years yet).  In the meantime I'm cooking more veggies in the shallow bowl of the 10 cups.

6 cups - Outer diameter 31.5 cm x 25 cm (H); inner 20 cm (d) x 10 cm (h) 10 cups - outer - 38 cm (d) x 28.5 cm (h); inner 24.5 cm (d) x 12 cm (h)
