is really very good machine & very helpful seller. is really very good experience to me

Thank you. The seller is very responsive. It has nothing to do with the seller, as he is not the manufacturer of the Quantum device, but the Quantum device software comes with a Trojan. Despite the seller’s reassurance I am not comfortable with this. I have seen the device working from someone else and the readings are impressive. I have yet to install this one and I probably won’t unless I get virus free software.

Very cute machines
