My son got the Leapster explore for Christmas last year, he was 4 then now 5yrs old and he loves it!! Before that he used to play with his sister's pink and gray leapster (the one before the leapster 2) and the old games and still does sometimes when his explorer is on the charger. His play time with it is limited every day and the only time it is unlimited is for long car trips (from Jax to Disney) or if we are at an appointment to help keep him entertained for a while. While Leapster makes a great line of products, the leappad might be too advanced for him right now. JMO
