Physically the light, buttons and dock are great. It's the software where no real care has been taken. Couple of things that are done without any thought.
First is the built in sounds to fall asleep to, beach, rainfall etc. All good except they are on a loop, which is fine, but the sound stops for a second before playing again. Not something you want your attention to latch on to when you're trying to fall asleep.
Along the same lines, when listening to your own music while falling asleep, firstly it will randomly play the same song again straight away on way too many occasions (like every other night). Then when the time you've selected to play music for is up. It just cuts out. If you're not asleep, then this activates your mind, which again isn't the point of this product. Two small issues, that should be easily to stop, that aren't. Very poor attention to detail. I should be being helped off to sleep, not annoyed off to sleep!
Been using the light for a few weeks and just lately it's not been on when I wake, not sure why, set-up is the same. The general set-up of the iphone app isn't great. It shouldn't be overly difficult to get the software working with the light.
