I doubt it. Not at the eBay price. Especially as they seem to expect returns and expect you to pay for them. This does not sound like a good sign to me.
The earlier WF-008s were supposed to be pretty good but the newer ones are supposed to be pretty poor.
I'm lately pleasently surprised with the quality of the newer budget flashlights. The Conqueror MX-008 is one of those. This flashlight looks good in the pictures, but even better in real. I compared it with a TorchLight from KD (the same as Ultrafire WF-008), because the size of the mirror housing is the same. The TorchLight is one nice lightning tool, but when you hold MX-008, it feels like a much more expensive light. I haven't take many pictures, because those on Manafont are very good. The anodisation is nice and even satin like type-III. The glass lens is not AR coated, but I already ordered 37.9 mm AR coated from KD. Although the mirror housing is the same on the both flashlights, MX-008 have inside of the housing painted matt black. Even the led emitter is painted black. Maybe this contribute to a slightly nicer beam compared to the Torch Light. The mirror surface of the MX-009 looks better than those on the Torch Light. Both flashlight have Q5 emitters, and I measured 19500 lux at 1m from MX-008, compared to 20500 lux from Torch Light. But, the current draw from almost full 18650 were 0.9 A at the tail cap for the Conqueror, and 1.5 A for the Torch Light. I'm planning to replace the original 4-mode driver with ShiningBeam 1400 mA 3-mode driver, and with the AR coated lens I'm expecting some 25000 lux :)
I've always suspected that at the around 20-30 mark shipped from china, they can do some killer lights. The problem with <15$ ones is that after you factor in overhead and everyone's cut, you're looking at maybe $5 flashlight and the emitter costs $2 or more. Hope these factories get their act together we get more like these.
