Small and light flash! In fact, I was really surprised at how light it is. Worked great with my Nikon. Fast processing is very good. Light quality looks great! Overall I am very happy with the V1. I could get rid of my 3 Nikon flashes now!? I have a Flashpoint R2 transmitter but I couldn't get it to work with the V1 without a camera so that was a bummer. I'm not sure how useful an AK-R1 set would be. The grille didn't help much, I guess I expected more. However, I look forward to using color correction filters. The possibility of adding accessories is very easy thanks to the magnetic connection. I think barn doors would be the most useful element. Godox now needs to make an S-type Bowens mount compatible with the V1.
