Fairly easy to assemble if you have a flat base to put it on. Took about 4 hours without help. The panels are light and easy to move into place and once it is all screwed together it feels quite sturdy. Even with a hasp and padlock it is not the securest and the doors could be easily prised open or even removed as the screws are pozidrive. 
Plenty of head room but it could benefit from having some hooks as can cannot screw into the walls.
