I don't understand the negative reviews on this. I've ordered three of these over the course of about a year's time and they've all been great - and I plan to order more! Tripp-Lite is very well known for standing behind their products - if you have a problem they will almost always make it right. The difficulty with $1-$10 items is that it's often cheaper just to purchase a replacement than it is to pay shipping on a warranty return/exchange. I can only speak to my experience, but I've had nothing but excellent quality from my Tripp-Lite products, including power strips, network cables, USB hubs and these iPhone cable - and I plan to purchase more.
