Is the quantum resonanace magnetic analyzer accurate?

Our suggestion is that for all customers,before purchasing the quantum magnetic resonance analyzer,firstly you need to know something of our analyzer.
1.Our quantum analyzer is just a tool to detect people's sub-health status,so it can't find the disease or cure the disease.
2.Our analyzer is based on western medicine theory to collect the weak magnetic field sensors of frequency and energy from human body through the hand grip sensor,and comparing with the standard data in the quantum resonance spectrum, use the Fourier analysis method analysis to get the result,according to the result and then give you some expert advice.It's accuracy is 85%-90%.The result is based on lots of the clinic experiments.
3.Some people think it's not accurate,it's not the quantum resonance magnetic analyzer itself not accurate,it's that they use the analyzer in the wrong way,especially when they want to get some comparision analysis of two different time.When do the compared test,want the result is accurate,you need to keep many data equal in the two different time.(1.the same computer 2.the same person with the same data(the true name,age and sex0 3.the same left hand)
