Review on 🔬 Enhance Scientific Exploration with the Listening Scientific Explorer Electronic Observing Device by Herthoel Yanda

I bought this product for ghost hunting. It arrived today in perfect condition. I checked by asking my son to stand in the kitchen while I walked out the front door and closed it. (about 40-45 feet) I spoke softly with my hands over my mouth and he could hear what I was saying. Great product, great price!
