The first major issue with the watch is the alarm sounds. When you use the sleep trainer, it will emit sounds according to the set time. They are very noisy and scared my baby for the first three days. You have to go to the alarm setting and set the volume to zero if you want to turn it off. The instructions don't mention this. I also thought there should be two different colors for awakening. One to stay in the room and be quiet and one to leave your room. There is only blue, so my child only pays attention to the face. That doesn't work very well for a three year old. You also need to set the trainer's time to at least half an hour before you want to use it, otherwise you'll have to wait until the next day for it to work.
