Review on Unveiling the Supernatural Secrets: Spirit Box P-SB7 for Ghost Hunting Enthusiasts by Donna Marshall

CONS: This is a very cheap product. Honestly it's not worth the price. FM can run fastest at 100ms, but am is 200. When I first tried it, it actually ran at 100ms. But after that, the fastest time on first use is 200ms. The internal speaker sounds like a headphone speaker. You hear almost nothing. The included external speaker is terrible. It got as loud as the internal speaker. Pros: it works. When I first used it I did a 2 hour session. Whatever happened, be it ghosts or other entities (I have yet to find out what or who I was talking to) could say a lot in the first session. It is recommended to use good brand batteries. The battery life is 10-12 hours per pair. The backlight on the screen helps a lot, although I wish the keys were backlit too. for every paranormal investigator. If it wasn't so expensive I would buy it for a friend as a gift.
