Does anyone use it and what do you think?

I have one that I got for a Christmas present years ago. It does amplify the sounds and put you on alert. But once as I was wearing it I heard the deer running, they were getting closer and I had no clue as to the direction they were coming from.(because humans need stereo or both ears topinpoint direction of sound) unlike a deer whose both ears swovel. Needless to say I learned a lesson and now when and if I'm wearing it I pull it out (I have it on a thread)so I can detect diret direction. Just wanted your imput.
