This charger has its positives and things that could be better.
Positives: once installed, it sits flush and is very unintrusive, it works well for charging my iphone 4. I have not tried to charge more than one item at the same time.
Could Improve: the build is a bit flimsy, the first one broke in half in my fingers as I was trying to remove it from one car to another (luckily, I bought two). Once you insert it into your lighter receptacle, I recommend you leave it there!
