content: pro's :great fun, portable.con's: hard to read LED except in darkness ,no off button.As soon as I got this toy I started playing it.but then ,I found out that in bright light I could not see the LED so I went in some shade.Now thats just fine except theres no shade indoors!so I found a dull light and used it.But then I brushed the yesbutton and no button would turn it off so I had to play it though.But overall if you have a dull reading light and you are patient, buy this product.
