On a recent episode of Shark Tank, Mark Cuban, and some of the other sharks, spoke out against negative ion technology. When Ryan Naylor for Esso watches gave his demonstration, Mark Cuban had some harsh words: “I’m allergic to scams, seriously; this is not new, its been disproven. What you just saw was placebo effect. Theres athletes that wear it. It’s a joke. It’s a scam. It’s not real. I’m out.”

Naylor admitted that he had no laboratory testing to back any of the claims he made.

Balance bracelets have become very popular in recents years, and many companies have come under fire for making false claims that cannot be backed by any scientific evidence. One of the largest companies to fail in this category is Power Balance, who was making $11 million a year before filing for bankruptcy because they could not back their claims.

LifeStrength, a company specializing in negative ion bracelets and technology is now speaking out, saying their products are legitimate.

“We have third party verification for every claim we make, and we can objectively measure the negative ions our produced (sic) by our product,” says Brand Hunt, Director of Retail Channel Development at LifeStrength.”

“Overall, we do everything in our power to avoid looking like the business on Shark Tank,” says Joshua Taylor ,a rep for LifeStrength. “We have never felt the need to defend our product because we’ve made the research available to our customers.”

Opinions on these types of products vary widely. Obviously some people believe they work, because they are being purchased in major retailers across the country. Others thinks there is not enough evidence to justify their business. What do you think
