I wrote a review back on 09/23/20 when I received the Scrambler. I knew I could make it work even though I didn't have a skull to try it on. Now after using it on 4 deer sculls to make European mounts, I does work to remove the brain matter. I boil the heads & then use it to scramble the brain. Then I use a power washer & wash it out. It is an excellent to & works like you cannot believe. If you do Euro mounts, buy this tool.
