Yes pick and choose products carefully that have been tryed and tested with replacement parts if you can, a seller is only as good as there supplier.
I personally like manafontand Jim has looked after me but I'm fussy with what I order. I would order from manafont before I will order from DX, DD, Focal point and so on, I don't order any thing electrical from eBay that is flashlight related cause I've been screwed more times then I've won.
The reasons for reviews and me doing 70 + hours of dishcaharge and charging is to show people what is ok and not ok to order as there is alot of yeah this is good and cheap but they turn out to be fake some times or the sellers are painful with incorrect orders and most people with out hobby chargers would not even know if a battery is ok or not.
Every one here wants to save money and get the best bang for there bucks but my short time on here I see the same people suggesting the same sites or untested products, people can say that about me and that's fine, but I see so many fellow torch freaks getting caught out.
Maybe I'm looking at it wrong or over thinking it as some times the deals are great and some times they are not, people talk about china being a lucky dip and this can be true, I might be crazy thinking it does not have to be this way and we don't need to spend big $$, maybe peoples expectations are to high from this cheap stuff and it's cheap for a reason.
So buy what you want from we're you want just becareful and never spend any more then your willing to loose on the net, that's the way I look at it.
