I have to say, having tried to assemble my first super (non-budget) from T's, the instructions are at best unhelpful and at worst, rubbish.
I don't have great knowledge or skill in working wood but assembly I am good at. However, these parts were not a great fit and the instructions very short on plain speaking.
It resulted in me making a mistake I may regret as I could end up breaking the super as I need to resite one of the inner walls.
Pissed off that this should happen, but it was a struggle, far more than I've had with some of the other stuff. Not looking forward to the budget ones now.
