okay so on Ebay i saw this item Newest Adjustable Focus Green Laser Pointer Pen Safety Key Battery Charger | eBay
It says "This laser pointer can be used for presentation, teaching indicator"
yet it also claims to burn through tape... Surely if it can burn through tape it should not be used for presentations, but its only 5mw. So is this worth buying? I want a laser to be able to atleast cut tape, but I want to spend the least I can.
