I was curious what the hype was so I only ever bought one to try and it was vouched by like 45 ubers... Happens to be all the guys friends and none even used it. It was one of the worst eBooks EVER. Didn't make a single dollar off of it, even when I had experience in the field it required.. And they denied my refund. For me it wasn't a loss, but a lot of people hope to make a few dollars off the eBooks and end up making nothing.
wouldn't trust a lot of them if it's in terms of making money
