Anyone ever use one of these? FM Modulator

eBay Link.

I've got a little battery, the standard little things with a 3.5mm lead on the end, runs off two AAA's or 12V output. IT's quite good, not too bad, but I want a better one. We have two cars so would like to switch maybe now and again.

It plugs directly into the arial port, so would be better?

What are they like? Thanks!

utter toss
you spend your money on a supposedly superior sound source only to make it sound crap by using these
thats not a dig at you but a general observation
these things are no way near as good as having a proper ipod controlling h/u
spend your money wisely and buy a decent h/u it will cost more but your ears will thank you for it
