That looks almost identical to the QRS (Quantronic Resonance System) which I have. I can say from personal experience, having used the QRS, as well as many, many, magnet, and electromagnetic devices, that I have not noticed anything from them.
The Molecular Enhancer appears to be an ENTIRELY different animal, and one that I find very intriguing. I will probably get that and/or the Violet Ray next (as soon as I can sort out all the different manufacturer/distributors of those devices).
