Before purchasing I contacted Coredy people on their website to ask if it would work with my robot but there was no answer so I took a chance and ordered it. I run Coredy every morning but I don't want it knocking over the Christmas tree. Before attaching the strip with the supplied tape, I thought it best to test how the robot handles it. He went straight for him and then ran over him. I returned the ribbon and reinforced the tree with heavy books covered with a wooden apron. Books worked better than duct tape.
