These are pretty cool but you have to determine if you have a use for them. They can make for an interesting way to do a pull down or t-bar row etc using these instead of just the bars but I am not sure they are really essential but they do at least give you some variety. Price has come down on these and got free shipping from rogue so not a bad deal.
These are cool and were a good price. I like this for grip training and especially as some grip contest had similar implements so I wanted to have same thing at home to train with. They came in a pair and I only kept one as I only needed one and gave other away.
I like this. I did not have as much trouble as others with it being stiff. This worked well for me because I needed a tricep attachment that would let my arms go up high enough at top of rep and not have weight stack hitting which is what would happen with my rope attachment.
