Sent off this morning.
I had five shaves, using the medium and aggressive plates. In short, the Supply SE doesn't do much for me despite rather a lot of experience with Schick-type injector razors. For me, part of joy of injector razors is their manoeuvrability and weight distribution. Like the Bunny, I actually found the Supply's head too bulky and the angle unintuitive. Unlike the Bunny, the Supply's Two Dot setting was markedly inefficient; the shaves were comfortable enough but not 'close' for my usual two-pass standard. Conversely, the Three Dot plate shaved closely but at the expense of comfort - the aggressive plate does transform the razor with noticeably more 'blade feel'.
Take these findings with a pinch of salt because I trialled the razor for only a week. The week was sufficient time for me to conclude that the Supply doesn't cut it for me but, as ever, my experiences are subjective...
