Third grade manufacturing
19 April 2019
I got a different colour (all black) and it broke during 3rd use at 30Kg Load, when it is supposed to take 40Kg
This item has a serious manufacturing defect.
See the image.
There should be a metal blocker at the top (a ring) + a metallic guard for the long opening.
At 30Kg load, the screw pops out through somewhere in the middle of the long slot (marked in the photo with a red rectangle).
People can get injured. My son was using and almost injured himself.
My recommendation: DO NOT BUY THIS.
Thanks to Amazon for arranging a refund.
