Dear Sirs/Madam:I sent a review of this item/purchased for my nephew for Christmas 2011. I did not see him till early this year and the product sat on the shelf because no one not a physciian nor police officer colleage, student or myself could figure out how this works. This doesn't come with any instuctions ????? And to our dissppointment this our second correspondence. Amazon is my only link to assist me so I will contact them if I do not hear back from you as the vendor.Thank you again.Mrs., Mr. Reina(209)532-7756R.I. REINA, M.D.
