This product works really well charging my iPhone 4S and my iPhone 5S yet is a bit slow in charging my iPad and iPad Air. The reason I gave it 2 stars is because it tends to heat up a lot, especially when I leave my device charging over night. I had to go buy a licences Apple charger and just use this one as a backup. Another thing that bugged me about this product was the really bright blue light it gave off. Not Good!!!!
