Hi, I have a Jetbeam M1X since I bought it there has been a flicker and loss of power if the torch is lightly shaken, not what I would expect from a torch of this quality, I did return it and it was sent back from the supplier stating there was no defect. I use the torch out at night walking the dog and at times the light goes off simply from the movement from walking and I'm left using my small AAA light. I've tried both CR123 and 18650 cells.
I have cleaned the threads and applied a little synthetic grease, also cleaned the contact point at the head of the torch.
Any ideas would be greatly appreciated as the light is currently confined to the drawer.
