This product feels solidly built and works for its overall function of charging my iPhone. As other reviewers have noted, after some time the unit does begin to get warm/hot to the touch. I use a MagSafe case with my iPhone so there is not direct contact. Charging time is good - not super fast but quicker than weaker chargers. The phone remains usable even when charging and the longer cable is nice. Overall a good product for the money if you don’t mind it heating up a bit.
