I bought this for my 3 1/2 year old and we both love it! He is easily able to understand how it works. He is very proud of the fact that he knows when it is ok to get up in the morning and I am thankful not to be woken up at 5am :) Another reviewer mentioned that they wanted it to stay lit up in the ok to wake position for longer... there is a setting to change the default wake up light timer to stay on longer... I have my son's light set to stay on for an hour just in case he does sleep in :) Another reviewer did not like that it takes batteries... so far we have not been burning through batteries, we are still on the 1st set, and I like that the batteries make it easy to travel with. Definitely recommend it!

Love the idea of this clock. My son loves to wait for his clock to turn green (and often hollers to me out of his room that it is, in fact, green). In that respect, it's great. However, they really fell flat in making this a battery operated clock (you CANNOT plug it in). Because the clock also lights up when you press the buttons on the feet, most toddlers will be inticed to press them over and over again. Between that, and the actual "ok to wake" light, the batteries drain quickly, and you'll find yourself replacing them and resetting everything (the time, alarm time, amount of time the clock stays lit, etc) on a regular basis. Another minor complaint is that the nightlight feature can only stay lit for 2 hours maximum. It would be nice if there was an option for it to glow all night.
