Wait! Let me get this straight. You are posting on a BB where we aren't supposed to discuss cheap, import tools and asking why you are not getting any response from a CHINESE company that makes them?
Why not just make your own tool post with plans from a US company?
Not only does it have all the accuracy of the best tool posts sold, but It is the most rigid tool post of any design, bar none. It is almost impossible to imagine a design that would be more rigid. Although it is not apparent in the photos, it does have individual tool height adjustment in each tool holder. And it is easily scalable to any size lathe.
Finally, it features, hands down, the fastest tool change of any post sold. The tool holder is removed with a SINGLE motion of ONLY ONE hand. And the new holder is installed in exactly the same manner: ONE HAND and ONLY ONE MOTION. Absolutely no wasted motion and NO TOOL is needed to change holders so you never have to look for "that wrench". Therefore, it saves more time than any quick change tool holder on the market. And this is accomplished with absolutely no sacrifice in the positional accuracy when reinstalling a tool holder. You can use the same dial or DRO readouts for multiple parts. No tool post is more accurate.
I created and sell those plans and I will always answer any questions posted either here or on the board where the plans are sold.

PS: The plans are not just drawings. They include a complete, detailed, text description of the construction process. I have had comments on how good they are. And if you have any questions you can always post them there. And I AM HERE EVERY DAY.
