We tested FPV Booster for Vision (non-Plus) with complete stock Vision aircraft and RE500 repeater. It reached around 300m (640x480 15fps) before boosted in open area. It's pretty much the same FPV range per DJI's specification. After BOOSTED, it achieved 800m (640x480 15fps) in the same area and flight path. We are pretty satisfied with 160% FPV range improvement. It may also help the highest 640x480 30fps Preview Quality, though FPV range would be shorter than lower Preview Quality
