Been using my axle with a landmine for a while. It's not the best setup, but it definitely gives me a long enough lever that I get a pretty good strength curve out of it.
This is by far my favorite tricep attachment. I love the powder coat on this thing. I know other brands make very similar attachments and I would recommend any that are similar to this
I've had to glue this thing multiple times cuz it keeps coming apart. When it works it works and I guess it's okay for the price. But this is what you get when you go and buy the cheap stuff.
Been using this as a hip circle for years and I don't think you can do any better. It might not be the most comfortable but resistance curve on it is perfect for warm-ups.
Great value. If I was to change anything I'd add a little bit of protective coating on the inside for the bar. Some of the nicer bars you put in there could get scratched up.
