Yep, I'm with you! I have done 8 flushes and gotten different results every time. Not the same type of stones after the first 4 flushes any one time. The last ones were all white! All I know is that if its not real then the data or results are inconsistent to support that or they would come out the same each time. Sorry skeptics.. you can't fool me.. the proof is in my returning health! :)
