new device out that saves gas, any good? (fuel doctor - fd-47)

A new device is out, fuel doctor usa, and was wondering if anyone has used this? I'm interested in purchasing but for $69.99 I wanted to hear some opinions on it. I've been reading some reviews but skeptical on who is writing them, so came here.
