Bought to check 5G, but found many other things too.
Very easy to use. Amazing how many things you suddenly realise are using energy on standby even when they are not actually being used. I was shocked when I saw my ninja blender was using loads of energy just whilst it was idly sat there. I switched it off at the power socket and sure enough the meter went down to zero.
Then I found that our door entry phone was a huge emitter of RF even when the receiver was in the cradle.
But I actually bought it for checking the 5G levels, and so far am happy to say I am not in as much of the 5G field as I feared I was, so it gave me peace of mind.
I was told this is the best EMF meter on the market. Having used it, I can only agree, it's absolutely superb. Easy to use, very accurate and well built.
