Looks interesting, why no info? - Laser Ammo Interactive Multi Training Targets

The product description would be more useful if it provided information. How big are the targets? What do they do? Does it continue to display where last "shot" hit? If so, how long? Will it display shot groupings? Does each target come with a stand so you can setup multiple targets at once? What do I need to shoot these with?
Just repeating over and again that these are good and durable is meaningless without clarifying the dimensions, functions, requirements, compatibility, and what they are made of.
Might buy this, but I'll have to find another web page that provides info.
