Well Ultra Dot came out with a green dot I was lucky enough to get one of the first batch. The other difference with this new one besides color is there are off positions between each brightness setting so should be a little quicker to get back to your setting without having to dial all the way around. I currently have a red Ultra Dot on top of my Nelson conversion but have two more bullseye guns in the works so not sure what I'm doing with the new one yet.
