I buy lots of stuff from China - especially those products that are similar to the expensive big brand products. I know the pros and cons and I can live with the moral and ethical issues, when I can get ten of something similar to the price of one.
I'd always wondered how they did it though - clearly copies, but how did they get the original?
One of my suppliers of lighting has solved this. I used to buy the 650W and 1K Arris Fresnels - the critical parts - the lens and reflector were very similar. The lamholders and focus mechanisms less good. They were similar but the metal was softer and if they jammed - which they did, I learned to NOT force the knob, because the spiral guide would just bend. However, the price enabled me to buy quite a lot and they're all still in use in one venue - where they sit on wide angle and flood a stage - they're fine.
It seems they simply buy a real unit, dismantle it - and then reverse engineer it - This I guessed, but then they simply pop them on ebay to recover the expenditure.
