used refurbished [SEP] received unit about an hour ago so i can not post reliability or quality yet as you can see the scuff marks in photo right out of the box i am thinking unit is a refurbished or used charger is not a factory box charger after market if it works does not effect me much other than it was supposed to have been new one thing i noticed real quick as well nothing about charging the unit in the manual not ta nothing disappointment what manufacturer does not include charging instructions so we will see how this goes over the next two weeks i will give an update after using this it was brought to my attention second setting light turns off when it counts down to seconds after giving it thought i am returning unit as i was supposed to have been purchasing a new unit like buying anew car with a mile warranty the salesman pulls your car around you jump in and happen to notice it has miles already on it you asked does it come with a mile warranty been it already has miles on it salesman replies no it comes with the standard mile warranty you will not buy the car same with the light it comes with its standard warranty bu i have no idea how many times or how long it had been used not the products fault it the sellers fault
