We have the regular Leapster, and my kids love it.
I am not sure if V-Smile has improved their systems, but I have literally gone through 4 systems. Never once was it something my children broke. Two times the games would stop "clicking" when inserting so it wouldn't read the game. Once, the onn/off button quit working, and then one machine just started shorting out while the kids were playing a game. I would call the Vsmile CS and they would immediately ship out another one without questions. I am so frustrated now because the current machine only plays about 3 of their games...but I am so tired of dealing with them. I wasted so much money on the games/system. BUT, I could just be very unlucky!! The games themselves are very fun, and they have a great selection.. also, the last time I got a new system was over a year ago, so the system itself could be improved.
