Since the chances are I will never be able to update this review because If an EMP hits there won't be a way to. I look at this as spending $60.00 for the hope it protects my vehicle if an EMP was to occure. I error on the side of this is either $60.00 that could save my life but if it doesn't atleast it was only $60.00. I recommend for the hope of peace of mind, but let's say I am not holding my breath.

Fits in the cigarette lighter as it should. Have no idea if it does anything at all

I purchased one for each of my vehicles. The center pin is not spring-attached and therefore does not allow the pin to be depressed to fit the socket well. The entire unit is barely fitting the socket and could easily bounce out. I installed these hoping they will still work when needed.

Very fast and easy battery placement. Same goes for AC placement device. Unable to review EMP results until actual usage, but have faith in Faraday bags and devices.

Protection was slightly below average.
