I'm having the samw issue here. I really just don't know what to make of it all. I really like the machine and I really would like to buy it. It all seems very confusing and I only want to use a fraction of it. I don't want to even give therapies through it. I just want to test foods. That wouldn't be any different to using any other machine. And I can't use any ohter machine because they all run off so much electricity and I am affected by it. So I really don't know what to do. I can't think what else to use to simply get on with my life. This machine tests everything in 4 minutes and then you can disconnect it. It's great! I can't think of anything better for the patient and the practitioner.
