Love the design and easy to follow instructions were invaluable for 95% of the installation.  Following the 4th step of the instructions connecting the water lines to the spout  was quick & easy.  However, due to the curve of the left side (hot water) 
connect, it prevented the use of the drain stop.  Finally "man-handled" the left hose curve forcing it into the correct direction.  This enabled easy opening and closing of the drain.
