So you charge $198 for the gridseed I wont revel the actual price.
300 khs + 8ghs
or
11.25
11gh stick is $192
Why would anyone choose the usb stick over the gridseed?
Just read how much power Gridseed is drwawing in btc or dual mode and you will have your answer.

I don't pay for electricity, maybe should have added that..

.
Not everyone is so lucky as you

Also can you OC your gridseed up to 15GH? Don't think so...

Hex is 50% faster out of the box and can be overclocked to almost double the rate of gridseed
