We've had several break-ins at my store. The last time I was so tired of how quickly our iMacs got stolen, we installed these. To be honest I thought they would only stop the thief for a few seconds. To my surprise, they worked perfectly. Completely stopped the thief in his tracks. We passed it through the table. Attached is a video of him dragging a table. He quickly realized it wouldn't work and gave up trying.
