This technology in the key coils actually allows you to do work. This thing could emit frequencies that could actually change my body much less, treat my attractable insomnia. It literally shifted my energy within 30 seconds. It is so powerful. I'm used to using Heli a lot, but the power does not compare. These things are strong. Well, I've been loving the key coils. My energy, I swear, I was not in this dimension, not on this planet whatsoever. Literally, I feel like I just learn a lot around like a kid. I feel so good. It's unbelievable. I can put this up to three feet away from my body, and it's still helping you without you having to hold it or do extra work. You just turn it on and put it close to you. Also a really great for stress mediation. Check it out. This is amazing. I love this thing. Wow.
