Review on Privacy Disturbance Conference Meeting Device by Kichwit by Josh Whitehead

This sign works for my purposes, I've just built my office/bedroom and several family members knocked and then walked in without waiting for an invite or someone knocked while I was on the phone so it's great is working. Please knock - when I'm free and have visitors. In a meeting - on the phone or not wanting to be disturbed at work. Do not disturb - sleeping, showering etc. From the office - if I'm not there and don't have to knock for 10 minutes. It attaches very easily and won't come off if you don't want it. Comes with extra adhesive strips so you can move it around if you like. Easily switch from one status to another by moving the red tab.
