I really didn't think I was going to find a pull-up bar solution for my small apartment. Doorway models weren't going to work. I definitely required something that could be stored in a much smaller space and wouldn't be so complicated to use that I'd get discouraged and not use it.
I somehow stumbled across the BULLBAR 2.0 online, and it's every bit as good as I'd hoped to find. The simplistic and clever engineering design of this is phenomenal. Incredibly easy to set up, collapse and store. It's stable and I feel completely safe using it.
It's every bit worth the cost if you want a sturdy, portable, compact and super easy to use pull-up/dip + bar. Feels like quality from top to bottom.
