I've been looking for a freestanding pullup bar for a while. Ideally something I can travel with and hang my rings from too, at least for some basic dips and back/front lever tuck work. Perhaps it's asking too much though.
Portable means lightweight/compact and that generally means unstable.
I found this:

It seems a bit wobbly but apparently if you get an extra top bar attachment and place it at the bottom, it makes the whole thing more solid.
Anyone here had experience with it?
