WE DO NOT SELL THE AQUAKITS. If you purchase this product, you are paying for us to modify your AquaKit.  
 
How it works: you mail your AquaKit to us. We will modify it by adding metal rings and hair clips. You pick the color of the hair clips.  We will then mail it back to you.
 
The $20 price is for one AquaKit modification. If you want two modified, you must purchase two units. 
 
Fine print: modifying the AquaKit may void your warranty with Cochlear. We are not responsible for any issues with voided warranties. Proceed at your own risk.
