Product name: Black Tourmaline Magnetic Necklace & Bracelet Combo

"The magnetic clasp makes it easy to put on and take off."
Black Tourmaline Magnetic Necklace & Bracelet Combo Reason(s) why I purchased from you: Tourmaline products seem to suit me well, and I liked the tourmaline sheet I previously purchased, so I decided to try the necklace and bracelet set.

Detailed review: I had severe neck and shoulder stiffness and was searching for something that would work for me. I first bought a tourmaline sheet and it helped with my lower back. That’s when I realized tourmaline works for me, so I bought the necklace and bracelet.

I wore them all day except when bathing. At first, I didn’t notice much, but one day I took off the tourmaline necklace to wear a different one with my outfit and forgot to put it back on before going to bed. I woke u

Product name: High Density Negative Ion Generator - Medical Ion Mini

"I get better quality sleep."
High Density Negative Ion Generator - Medical Ion Mini Purchase reason: Very informative website. The Medical Ion High density mini package came with an ion detector which I really wanted. The information from your website convinced me to purchase your product especially the Medical Mini with the Ion Detector.

About effects: The Medical Mini really changes the feel of the bedroom. It allows for a very relaxed and restful atmosphere. I get better quality sleep. In combination with with the Air Tamer, you can have ions anywhere. The Ion Detector combination allows you to evaluate the performance of the ion generator. This is crucial if you have the cheap ion generators to see the difference in ion output effectiveness between the cheap ion generators vrs the more expensive but higher output products from Ion Trading.

Other comments: If you are serious about negative ions, the ion detector is a must have. Better than a detector is an ion counter but those are in the $1,000+ range. The detector is needed to ensure the ion generators are working and also provides a means of evaluating cheaper ion generators.

Product name: AirTamer A320 White | Personal Air Purifier Necklace

"Ion output strong and measurable. "
AirTamer A320 White | Personal Air Purifier Necklace Purchase reason: Very informative website. Your philosophy is to educate and thus justifies the cost of your products. This is crucial in the current market place where cheap imitations are rampant. After becoming familiar with the presented information, it be came obvious to get the higher quality that your products deliver if you can afford it.

About effects: The output from the Air Tamer was strong enough to be detected by my Ion Detector that I purchased from you. The cheap ion generators I bought from Amazon did not produce any detectable output on the Ion Detector. This unit makes a difference in my breathing and its also portable. You can take it anywhere. I hope it will function for a long time and I think you can replace the carbon filaments if it gets worn out. This allows the benefit of negative ions anywhere any time.

Other comments: Negative ions make my sleep much more restful. The question becomes at what price point do you have a device that produces enough ions to make a difference. For me my health is worth the best quality available and takes the guess work out of this question. I think Ion Trading products provide the best quality available.
