I purchased these over a year ago and on at least 5 occasions now, I have used the website chat and email contact to ask a simple question for clarity on the use of one of the conversion files. I never even get a response, acknowledgement or anything for that matter. Also the test footage advertised was non-existent and this point was ignored for over a year now too. I was patient before reviewing, but now realise they just want your money and wont assist any further at all. Not impressed. I am not asking a lot, I have one simple question which should be a 10 second answer if that!
