Replying to Oakley Helmet Kit...bullshit

Ive been hearing a lot about people who just need the oakley helmet kit for their goggles. Is it just me or is this 'Kit' just a bullshit piece of junk designed just so Oakley can suck $20 more out of you on top of the $130 they made you pay for the initial goggle. I have A frames (only cuz they cost $40 on sale) and they are fine on my helmet. Capitalism is really starting to suck.
If anyone can tell me otherwise of why this product is so neccesary id love to hear.
