Query: Design Disaster & Dopey Documentation

Exceeds Refrigerator shelf width due to bad design of unit top. Will not fit straight to allow water dispenser to work inside Sub-Zero refrigerator. Idiotic two-piece unit cannot be filled separately due to difficult water spout fill height. Refrigerator door will probably break spigot within the month, or water spigot will be contaminated during fill process in sink or from counter. PUR's design department probably from North Korea because this does not match US dimensions. Impossible to find specific information about what the water filter is made of or what it actually does. No documentation on types of plastic used or if it meets food standards. Avoid this product as it appears easy to break when attempting to clean.
