Ordered a Sunday night received on Tuesday, two days reception OK (amazom premium). Unpacking and setting up the battery (supplied with the pen, only good point) and then I press the button, I see the laser beam for 1 second and nothing more ... After several attempts, then battery change, I makes me obviously, the product HS after 1 second of use, probably a record !!! If you are interested go your way, as for me I will see how I can get a refund.
