The equipment was supplied by Amazon super fast. It works great and much better than its predecessor and at a very reasonable price. Overfoaming, a common criticism of rice cookers, has never been observed. So why not 5 points: 1) The unit is (with us) only for 4 weeks running, but several times a week. 2) the inner pot is made of very thin material, which is susceptible to scratches (already happened).
