Because the price was high, I did not purchase it here, but as I can post the review, it is for reference. It was the use for greenhouses in Hokkaido. With less than 50% of working days, I used brushes for 2 years with the use of about 4 hours a day. Perhaps I think that it has not been sold in the monotalou, but since the pump of the engineering is sold also in the home center, I think that comparing the price there is about the same. Although the story goes back, since the carbon brush which is a consumable item is not handled directly by the manufacturer, it becomes a customer note at the handling store. By the way it is 1 co 1450 yen. * 2 It takes a real double because it is necessary. Since it is a business item, we recommend that you purchase considering the destination of expendables. High power is good for performance. It's just chocolate and ursay.
