I'd say....
ho hum, it works reasonably well overall, but like a lot of things you realise what you THOUGHT it would do isn't what it does, but what it does is in line with what is claimed for it.... it produces turn points, and I for one think it's very interesting to see this sort of thing coming up when predicted. I'd also say you you could spend 24 hrs a day drawing lines on charts, and maybe I'm thick but I often had to print rather long period charts out to find turns in the near future.
For trading - the best use, at a guess, would be to predict the turns and then trade normally - when you thought you'd spotted an entry you could compare to predicted turns and if they coincided it'd perhaps add a touch of confirmation, making you happier to get in a bit earlier. That in itself could improve returns a fair bit.
I bought it, I have a sort of annual budget for checking interesting things out, RM is one of half a dozen I looked at this year. Do I trade using it? Naaah. Some might though, it's not without merit - I personally didn't feel compelled to follow it.
