I was quite impressed with the quality of this bar. It was purchased for my mother to have a lower starting weight on pushing exercises. The shaft is aluminum and the sleeves are steel. The spin of the bar is very fluid, with no clanking radially or axially. The knurling is also nicely aggressive, about on par with an Ohio Power Bar.
The current options on the market, while amazing, didn't have the capacity to hold a full 6 pack of brewskies, or 45 pounds of American Iron. With this XXL model you don't need to be limited by things like practicality.
I used this to add a foot plate for rows onto my Bells of Steel plate loaded cable tower. It's functional but definitely not high quality. The hinge and pin mechanism has enough slop that when it's locked open the pads sweep back a few degrees, and it's somewhat difficult to get the pin holes to line up.
It's strong, sticky, comfortable, lightweight, easy to move around, and stands well on it's end. It was also a great value at $180 when I picked it up.
