We have a "Leapster." My friend's have too. It's great!
It teaches children "educational" skills... but in a fun way.
I would recommend it.
Amazon.com has them... and usually at a discounted price with free shipping. Walmart online also carries it.
Both my kids enjoy it... my eldest being 5 going on 6 years old, and my youngest at just 24 months old. They BOTH use it. It's great in the car or anywhere to keep them occupied.
I have not found any "dislikes" with the Leapster we bought...it's been dropped and is durable, no breakage, not problems, batteries last awhile, we also got the case for it... it's a great fun/educational toy. I rate it 5-stars.
Good luck,
Susan
