Butt-Out Tool

Anyone ever use one of these?  Does it work?

One of the more unpleasant chores of field dressing now takes just seconds to accomplish using the innovative Butt-Out Tool. This tool is the fastest, easiest way to disconnect the anal alimentary canal from deer or similar-sized game. Immediately after harvesting game, insert the Butt-Out Tool into the anal canal and twist until it grabs the membrane. Continue twisting another half turn, then steadily pull the Butt-Out Tool out of the canal. Extract 10” of membrane, tie the membrane off and cut. Its time-saving ease of use makes this the tool every deer hunter needs in his pack.
