Anybody using one? How is it? It also looks like one could do this
themselves with a cheap Stanley Hips target or buying your own foam and stuffing the center with clay.

They claim to use a specailly formulated clay that doesn't stick to the shaft. I wonder what it is or if you could just buy standard clay
and mix some silicon grease or vegitable oil with it.

Has anyone tried it?
TIA
