Looks good, likely to work well, of Apple's usual, good quality. Except it is not compatible with iPad - it will probably charges an iPad, but it is not listed as compatible with iPad. A good guess is probably because it accommodates a variety of iphone casings and in doing so, it does away with a backing; Without a backing, iPad is too heavy for the lightning connector.
a charging dock is good for a few usage scenarios: using iphone as a clock/alarm clock and keeping siri activated and in stand by, for example.
