I think the main reason I really like this product is A it's black (I really like black electronics) and B it's low profile. Basically it barley sticks out of the lighter socket in your car, which is great. I already own a similar product for all my automotive charging needs but this one really catches my eye. The 12V DC adapter that I currently own sticks out over an inch further then this one does. You wouldn't really think this is a problem but because of the added length my charger tend to hang a pry the adapter out of the socket or at least dislodge it enough to quit charging my devices.
There are my thoughts now. Go buy this because it's good, handy, and will save you money!
