I sent a V10R Ti to Barry for etching removal and a groove mod. The light came back yesterday, and the changes made are a major improvement in this fine light. The feel and grip in the hand are quite different than before, and much better. This change is not merely cosmetic but very practical. Visually, too, the modded grooves seem more harmonious with the rest of the light. The V10R has a great UI. Now, with improved feel and structure, it will be all the more enjoyable to use. Thank you, Barry!
