We could probably have a hundred reviews of modern GEM razors, and we would probably end up with a hundred different impressions.
@Errol has given us a less than glowing review of the Sabre V1 L2, and now likewise for the V2 L3. For a while I had wondered if he just didn't get along with that blade format, but his impressions of the Vestige, and to an extent the WR3 belied that. (Page 88 of this thread: I can't see it in the index, which is mostly out of date now.)
The Vestige (++) BTW is still my #1 choice for GEM.
