Using the device is so easy. Just click on a button on the right side and then tap on somewhere on the map. The sheets are easy to change and the boys had no problem figuring out how and what to click. We did have some spots that we tried to tap on and it didn't work, but it was more so getting used to what each map did and where to tap the pen. The On/Off button and volume works perfectly and we have no issues with it. Like I said, the iTikes Map is easy to use. My boys can easily change the maps and tap around. I was amazed though at how long my boys sat and played with this map. There are quizzes and games to play with three different levels, so it does grow with your child. My boys don't use them yet, but they love clicking around.
The carrying handle makes it fun and easy to carry around and there are a lot of educational aspects to it. I think this is really a great device and see us getting a lot of use out of it! There is always room for improvement but what I like about this is its both old schools (maps and pen) with new school (iPod/iPhone.)
