Originally posted by voyager13 Yes I suspect the threading may not be of good quality (as the expression goes 'you get what you pay for') Still would be great to know from someone who has purchased them from ebay to find out how long they last. I mean if they last 1-2 years than perhaps not a bad investment for the sake of just getting the adapter and rings, and then perhaps investing in good quality filters to fit on them. Who doesn't like cost-cutting?
Why would anybody try these? The original Cokins are already comparetively cheap and crappy, why even bother to buy even poorer quality. Even the Chinese can not magically produce good quality for nothing.
If you want Cokin compatible filters for cheap, which still provide useable quality, you should look out for the Kood branded filters. I have the Cokin CPL and the Kood CPL and the Kood produces far less wrong colours and is all in all the better product. But in reality I never use it.
If you want really good filter quality, that starts with HiTech and then Lee and other brands, which you can still use in the cheap Cokin holders. The Chinese made holders and adaptor rings are fine in my experience and can easily replace the original Cokin ones.
