Was able to climb about 3 stories up before legs were getting tired. Ran rope up and around branches took some time. Seems like spikes were great, although its sketchy when not knowing how the health of the tree was because it needed removal, and no safety net down below. I ran safety harness lines up top as I climbed up I secured anchors and ran my lines tightly around the tree trunk. Tree was probably 5-7 stories tall. Using at your own risk. If your legs are strong this is for you. Purchased climbing rope etc. Separately. Thanks for the fast shipment. Purchased about a year ago already lol. Catching up on paperwork here. Note the spurs are easy to trip on baggy pants and fall on the ground when walking.
