Probably shoddy
I was able to use it, but the bearing assembly of the rotating part is not right.
The rotation at the time of jack-up is terribly heavy because of it.
As delivered, the grease of the moving parts was dirty and covered with iron powder and dust,
I took it all apart and Greased it up again before using it.

When opening and using it ... It is useless sucking air! There are about 20 cracks in Pipe.
It takes more than 4 days for delivery, it is ineffective with defective items!
To be honest, it was disappointing. For the time being, Pipe was connected upside down, the cracks were blocked with Vinyl Tape, the scale was adjusted by Scale and adjusted for Level. Can you accept it according to returned goods?
