I tried the free trial once and didn't like it. I couldn't work out how to use it and it looked like I would have to hand over money to see if it worked.
If their turning point indicators are often better than 90%, why on earth are they selling it? I would use it to make a fortune, not try and sell the software. 90% sounds good but they don't mention the size of the reversal. It might be too small to trade. Having looked at a few of these websites, I don't trust a lot of these claims. They don't seem to back them up with clear trading records that are independently verified.
