I think post #2 answers the how does it perform question and yes the value is in rarity. They shave, if using a #9 setting, like my Fat Boy also at #9 which is to say very well for me. The bottom Dial is the same for me also on the same setting. From experience I do not think they perform poorly.Although I have zero personal experience with Gillette Toggles, I've read online from people who have and that they found them typically performing poorly. If true, the premium price commanded speaks to the rarity, rather than the performance.
