I purchased this program and it does not work. I paid for their most expensive one and its the most unreliable software. On that note it does work every now and then but no where close to 90% success rate. And as someone mentioned above that how many spins does it take to have the winning number to show up and how you calculate the success rate? Basically what they say is for 2 proposed numbers you spin it 18 times. Now if you spin on 18th spin you are breaking even. you can win ten times then lose one bet you are down 36 units. In fact I just played an hour ago. first session won 6 units then next one was a loss of 36 units. You can not win 7/8 times in a row with any of their software. RCM M claimed to be their best software is complicated and you can not simply work it out.
I have asked for a refund which they don't provide. Yes you can do a trial with them and you might get a win during that period. Its only because casinos software will let you win if you are a new customer. But I never had a session where I could come ahead. I won 5/6 with a winning of total 10/15 units then hits the loss. Its not a long term winning thing whatsoever.
