I needed something cute and simple with a big digital display so I could see it in the pool.  This watch works great for that and for me.  Its cute enough to make me happy without being too kiddy.  Who doesn't love Mickey?
It did not come with instructions but setting the watch didn't take too much effort.  I did run into a little trouble when i accidently set the alarm, but somehow I did manage to turn it off. Not that I would have read the instructions anyhow.  :)
The watch is kind of small.  I can wear children's watches and gloves to give you an ides of the small hands and wrists I have, I like to wear the watch loose and have a little extra room.  If you have a big wrist you might have trouble getting into it.
