Product is good..Assembling is litle confusing. cataloge privided with it,1 Assembling tools were missing.. Wrenchs for tightening were missing. I bought it from outside to assemble it. from T part (elbow) Screw 1 is so tight. need to hammer. & Packaging was worst. tools packets was toren & opened. package also torend or little brocken with big hole. However Product overall is OK. Used flat , incline & decline too. i likec it . & Sturdy also. Now using good.
