eBay's cheapest pile of crap USB rechargeable LED head torch.

Who even came up with idea of a head torch that can't even be aimed into your field of view?
The circuitry is fine. The LED panel is OK (wide angle COB). The case is mostly great.... but it fires most of the light outwith your field of view.
It's like an LED bike light with a head strap on it. Maybe that's its intended purpose, although it seems a bit wide angle for that. Am I missing something? It just seems so bad for the quality of construction.

At 4V the white LED array passes 450mA
At 3.6V the white LED array passes 300mA

At 4V the red LED array passes 260mA
At 3.6V the red LED array passes 210mA

The processor cuts off at around 2.7V

Provisional lithium cell test indicated a capacity of 300mAh.
