    Precision and portability for a low price

    Posted by Nelly on 16th Jan 2024

    I've had the Safe and Sound Classic II for about two months, and I actually have the Safe and Sound Classic I as well. The S&S Classic II is a step above and seems to be even more sensitive as the ratings I'm getting are higher. Perhaps there are more sources of EMF in my environment which is very likely as those around me are using more technology that emits EMFs. I love the small size for its portability and the option to hear the sound of EMF, and even though I can't decipher it the variation is interesting to notice. I feel the open box quality is very good also.
