Cal Steam Company Reviews
5 out of 5 stars, based on 1 review

  • By John G.
    July 15, 2011

    I find CAL SDM, is a very honesty business, J.Kim is a strong Christian man who is taken advantage of by others. Mr Kim tries his level best to satisfy his customers by providing quality goods and fair prices.
    People think they are living in the 1940s and that he should ave prices from that era, reallity is it is 2011 and the economy isn't getting better, but business must keep going and it seems that people want something for nothing. Mr. Kim tries to help as much as the economy allows.
    Thank you (Mr. Kim)
