Not difficult to assemble and seems sturdy.  My complaint is that the first day the hot sun shined on this box the lid warped badly out of shape.  To make matters worse Wayfair's sight will let my enter a Chat session and type my issue but then it keeps telling me it can't send it.  So, at the moment I am stuck with a warped lid and not communication - unless of course I want to wait on hold for a long time.  There does not appear to be any "fix" for this except to replaces the lid which will no doubt do the same exact thing.  Bottom line is that this unit might be "UV Resistant" but it is not suitable for sitting out in the direct, hot, sunlight.
