Love love this gazebo!  I had it installed by them which was worth it to me.  They did a great job.  Its a heavy duty gazebo and I did not bolt it to concrete as its so heavy. It will not move.  The only thing Im disappointed about is, there is no room to hang lights.  Im trying to figure out something but not seeing anything to put them on.  All my other gazebos had rails that you could string lights on.  Thus one has a track.
