Several years ago, Ernie Els' son, Ben, was diagnosed with Autism. In 2009, Ernie established the Els for Autism Foundation, with the long term goal of funding an Autism Centre of Excellence.

"Autism hits families hard and I'll be fighting for the rest of my life to try and help others in the same situation. I hope you'll share an interest and join me in this fight." Ernie Els

I-ONICS are proud to sponsor Ernie Els, and even prouder to support his foundation. For every purchase of this special edition Power Sport band, we will donate a significant amount to support this worthy cause. For more info head to els4autism

In our modern life, our bodies are overwhelmed with positive ions, which are emitted from electronic devices such as computers or phones, causing a significant imbalance in our bodies' natural ion level. I-ONICS equipment releases negative ions which instantly correct this so your body can perform to its maximum potential. Comparisons

I-ONICS is the most powerful product of its type on the market today. You'll probably have heard of Trion:Z - on their website, they boast that theirs delivers 600-800 negative ions a second. Not bad. It certainly beats Phiten, who we tested at 5, and Q-Link, who we tested at 16.

I-ONICS deliver 1100 negative ions a second. That's more like it!

Anyone can tell you wearing something will give you certain benefits, but we can't think of a better way of demonstrating it than with some tests you can try at home. Try all of these tests first without the band, and then with, and see the difference.

Strength and Power

Stand with your feet shoulder width apart, and raise both your arms to your side so they are level with your shoulders. Have a friend push down on your wrists as hard as they can, and resist with all your strength. Now try again with the band on, and ask your friend how much stronger you felt.

Flexibility

Stand with your feet shoulder width apart and raise your right arm out straight in front of you. Move your arm slowly clockwise following it round with your head as far as it will go before its uncomfortable. Have a look at where you are pointing. Now put the Power Sport band on, and try it again.
