Title: skip it
Review: Spend a little more, and buy a name brand. This product comes with no instruction. Though it's simple to figure out, you need the instruction if the darn thing doesn't work. The laser would come on when you put in the last battery (it touch the side of the casing.) But as soon as you screwed the end piece on, nothing works, even with holding down the "pressure sensitive pad". So SKIP IT!!mgso
