I really do not like privacy levers (or knobs) that have the "push button" or "turn knob" (that is used to lock the door) in the face of the handle itself.  I think it completely ruins the clean look and design of the handle.  
These levers have a thin "push button" (about the thickness and shape of a small thin dowel) that is underneath the level in the escutcheon plate which has very little impact on the overall look of the lever.  Unfortunately, Wayfair does not have a picture on the site of the privacy lever and I had to call to ask where the push mechanism was located before I ordered them. (The Wayfair rep quickly responded to my question.  Great service!)  I bought these levers in the polished chrome which looks very expensive.  The only issue is that they show finger prints similar to the door of a stainless steel refrigerator.
