Yeah it has been around for a long while, you really need to do your research on it I have purchased some things maby done like 10 fiverrs which are really good but then you go for other things and they do not provide good results at all and it is like blowing money.
Also another thing to watch out is the time of delivery, I purchased one thing from a guy with like 150 feedback all good, he took like 15 days to make the video LOL, but it was good =)
