Query: pen doesn't work

I was very disappointed with this product. My 2 1/2 yr. old twins got this toy for Christmas & were very frustrated with it because the pen doesn't work if you hold it at an angle. You must hold the pen straight for it to work. My 5 yr. old didn't like it either. I ended up returning the toy for a different magna doodle with a better pen.
