When I got the package today and opened first I wondered what that is: no guidance (not just difficult but I can imagine that some problems had so) when I screwed things together, of course I saw the really poor workmanship which welds ... well. The best part is, however, that I had to bend it the two devices so I could use them at all, bent and shaky that I can say. However, I must also say that they mean about 95kg easily cope and I (after I had it straightened out) therefore could train.
