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 doesn't 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. 3-2-19 after using this, it was brought to my attention  90 second setting, light turns off when it counts down to 10 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 30,000 mile warranty. The salesman pulls your car around, you jump in and happen to notice it has 10,000 miles already on it. You asked does it come with a 40,000 mile warranty been it already has 10,000 miles on it?  Salesman replies no, it comes with the standard 30,000 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.
