I purchased this a month or so ago, and was sceptical given the low price (I got mine for £3.99 including postage, from Amazon) and mixed reviews.
On opening the product, it is exactly as shown in the pictures provided. Looks good and Apple-esque in style. I have a 2009 Toyota Yaris and found that, while it does fit a little loosely into the cigarette lighter, it works absolutely fine and doesn't fall out. I've seen reviews where people have found it far too small for their car's cigarette lighter, but for me that wasn't the case - or it didn't affect the product's performance at least.
Not being very tech savvy, when I initially bought the Auto Kit I was under the impression that it would both charge my i-pod and allow me to play songs through my car stereo - in hindsight, this was a bit naive, and I should have done my research. But at that price, how could I complain? Having said that, I don't think it was made clear enough in the description that you need other equipment (i.e. a cassette adaptor or an aux-in port) in order to use the product as described. I have a CD player not tape player, so had I realised I would have gone for something different.
I now have an FM transmmitter which I found for pennies in TK Maxx (and which works amazingly, by the way, in case any of you have read reviews about the sound quality provided by transmitters being terrrible) and use the Auto Kit only for charging. As a charger, it works just fine, and I find it useful to have in my car glove box. But it certainly isn't anything special.
Honestly, this piece of kit isn't the best (was it likely to be, at £3.99?!) And there are cheaper i-pod car chargers that you can find which I'm sure work just as well. I think the description is misleading (at least to those of us not familiar with tech speak) and wouldn't recommend it as a charger (given that some people find it doesn't fit their cigarette lighters) or means of connecting your i-pod to your car sound system.
