SUPER SIMPLE AND EASY TO INSTALL!! I although had to use the the two center screw holes rather than the outer hole they want you to use in the instructions when installing the base which still worked perfectly. Packaging was great, undamaged and marked accordingly. Took me maybe 30 minutes to install altogether and Im 5 months pregnant! Wish it was a couple inches wider though so I didnt have so much wasted space between the units.
