Leapfrog Tag Junior - anyone got one?

[bgt]

Has anyone got a Leapfrog Tag Junior, what did you think of it? is it worth the money?

Ds2 got it for his second birthday and loves it. He uses it nearly every day.
However my Mum got it on special offer and 2 books on an offer too. The books seem expensive to me but there always seems to be offers on.
