I WAS REALLY SUPRIED AT THE QUALITY AND EASE OF ASSEMBY. I TOOK MY BOLT CUTTERS AND CUT THE L PART OF THE ALLEN WRENCH SO I COULD USE IT WITH MY ELECTRIC DRILL.  IT MAKE ASSEMBLY MUCH FASTER AND EASER. JUST BE CAREFUL NOT TO OVER TIGHTEN AS YOU COULD DAMAGE THE WOOD JOINT.   

Pros: GREAT VALUE 
Cons: NONE THAT I COULD THINK OF
