Ishikawa Island, this brand of excavator is not very good in China market. A few years ago, I heard that there was a joint venture Ishikawa Island in Xiamen, which was not clear. The overall performance of the machine is still good. One of my customers has the same model as yours. His new machine hasn't been repaired for several years, but I'm not sure whether it's an imported machine or a joint venture. It is estimated that few people use this machine, and we seldom see it. I'm not sure about the specific long-term performance, but it's a Japanese machine after all. Even if it is a joint venture, the quality will not be too bad. It's just a little troublesome to replace the accessories.
