Seems to be a small box on a tripod that includes a powerful laser diode (although not that powerful as lasers go they quote 800 mW at maxpower with their shield thing in place for comparison my laser cutter is 40 watts so about 50x as powerful and that's hobby grade class 1 relatively low power laser)
Seems some fairly significant risks associated with this thing they show their hipster users just running round lasering everything in sight with no safety goggles no thought to fumes or other issues most laser cutters and engravers have sealed work spaces and extractor systems to get the smoke and fumes out. If you are not careful and use them on the wrong thing lasers cutter can cause toxic fumes to be released. For instance cutting or etching PVC is a big no no as it releases chlorine gas.
Nice idea I guess but seems like a health and safety nightmare
