I used one ONCE. The pressure from the butt basket cut into the back of my thighs and made my legs go numb. If you let yourself sit down inside the butt basket to relieve the pressure on your thighs, you are nose to bark with the tree and have no mobility as now you are using your knees to keep away from the tree. Additionally, being in a tree with your legs locked wears on a guys knees, ankles, and feet. I was using both a tree spike and a branch to put my feet on and the tree spike started to make the arches of my foot ache as all the pressure was on the 1/2 inch space of the spike. I had to keep varying the pressure on my foot which made me make LOTS of unnecessary movements. Did I see deer? Yep. Would I use one again....NOPE!!
