Overall, a great deal. Price was reasonable and quality materials make for an overall bargain. Well documented and easy to understand...I did the installation myself ( I am NOT a carpenter or builder ) !!!
My only problem was getting the lag bolts to FULLY set without studs. I used a header board ( which was suggested in the directions ) and set the rubbery anchors in the drywall and placed the header over, I should have put the anchors in the header to do a more solid job. 
I was surprised at how effortlessly easy it is to slide that heavy door with your rail...it looks great too !!!
Momma was real happy  
Many thanks for a well thought out and solid product.
