Sean,
Geez you got those QUICK!
The rubber feet should be on both magnets (inner and outer), well mine are anyway. I don't think it's that big of a deal. Just use the rubber footed magnet IN the tank supporting the Stream/Wavebox. That way it will grip against the glass. The magnets as you now know are pretty strong and the rubber feet are pretty sticky, it's not like you can move the Streams around like you would a cleaning magnet! Roger can probably get those for you if it is an issue.
Back to wrapping,
Luis
