Easy to assemble. The screws pull it together pretty tight and solid. The glass panes are nice. I like the fact that the rail hardware is one solid piece. They could however wipe all the MDF dust off of the parts prior to packaging.  This would have made it a perfect experience. There is just enough slack in the fittings that you can center all the parts, especially  the bottom rails and styles to line them up perfectly  so the floor guide will not make noise when transitioning from the rails to the styles while opening and closing. If you don't do this it may be a little  noisy.
