After many years of suffering through the many operating [and design/manufacturing] flaws of another electronic soap dispenser, the Delata DESD-751 is a breath of fresh air. Its PIR sensor is well-optimized for object distance sensitivity; working only when asked to. The [remote-mounted] polypropylene soap ‘bottle’ holds an ample 1000ml. of liquid soap. The installation/operating instructions for the unit are thorough and well-written.
My only complaint would be the non-inclusion of an optional ‘key fob’ 4-Function remote control – the most-important of those functions being the soap quantity, which for my uses would be helpful from the get-go.
