Scam. tried it and feel no difference. even tried before and after with an EMF-meter. Talking with customer service they say that, that is not how you should measure it and that Qshield is a "passive product" that can't be measured. Will probable not get my money back since me as a user has therefor no way of proving it doesn't work. Even though that's how they show it on the website how they "prove" it's power using an EMF-meter.
