nah, you split them up or sell them to people as fitted.
ive little use for the USB adaptor, but ive kept it in a box, itll get sold fitted for £30/£40 at some point.
Well i bought it this morning and am waiting for problem to reoccur before i open it but mines been fine all day.
its a good piece of kit for the money though, im quite impressed at it for £50
I might even keep it instead of mine if mine proves ok as its better than mine. Both antenna detachable, something some of the earlirer models lacked.
