Has anyone done a simple test like throwing this over a home wifi box to see if the signal disappears?

My wife and i did the cellphone test. ( put cell under blanket and try to call that cell). Seems to block signal, which is what we hoped for as my wife is currently pregnant. She drapes over belly while doing work on ipad to protect baby.

If I cut it and put it between my phone and the case would give protection from emf without affecting the phone's activity?

It depends on, Place the fabric between the phone and your head. > Do not < wrap the phone in emf-fabric, completely! This has the consequence that the phone work more! to get reception. The result would be more radiation.The best solution for cellphone cases: block only one side of the phone case. The side that is closest to your head.

Would this shield the emf radiation from regular aa batteries if i wrapped it round the flashlight? (i have to hold it for long periods of time)

Hello,For Best Protection, you should wrap the emf fabric around the batteries. Then wrap a nonconductive fabric around the emf fabric, to avoid contact to the flashlight casing. ( a plastic or foam material would work)Please let us know if we can enhance our service to you in any way.Thank you

I just bought this and am very excited to try it out to block my wifi and also the electrical poles. Do i need a grounding wire to connect to it?

When I first got this cloth, I threw it over my router and immediately lost all signal to my tablet. It will probably work better with a grounding, but it seemed to be quite effective without it.
