This unit is about 30 lbs heavier than many other 10x10 gazebos.  That extra weight went into the frame, plus having both netting and solid screens.  Overall quality seems quite good.

The installation instructions are readable and complete.  Most of our installation was done by myself, with my wife needed for maybe 30 minutes to hold the frames up while they were being connected.  A third person during that 30 minutes would make things easier, but not necessary.  Two people makes putting the canopy on much easier - it would be fairly difficult to do it yourself.  They supply two cheap wrenches but do yourself a favor and get metric socket and wrench sets - everything is 10mm.  A step ladder is pretty necessary, especially if there's only two of you.
