I doubt you have actually ever visited the Jinan Blue Elephant CNC Machinery Co., Ltd. factory in Shandong? Which is relevant to Zoprano's thread. Well, I have in 2015 and can vouch that they are first class people.
I also doubt any other member has as well. So if you have been there and have first hand knowledge how come you did not part with it to the OP. A forum is a two way process.
