I was a bit apprehensive about purchasing these as other reviews stated the videos were SO boring and therefor failed to keep their little one's attention. As one reviewer pointed out, what is boring to an adult isn't always so for a child, so I figured I'd give it a try. BIG MISTAKE. I bought the 4 disk pack and I'm really kicking myself because after popping in the "Meet the Letter's' DVD we only made it to the letter D before the kids were over it. Literally, there is nothing more to this DVD then that they flash the letter on the screen--and then say the letter over and over. You might as well go get yourself a set of flash cards and use those with the kids--its essentially the same as this DVD.We have Leapster's Letter Factory and both my boys LOVE it. Now I'm wondering what I'm going to do with 4 worthless disks that aren't going to be watched and that got a total play time of 7 minutes. ;/ VERY dissatisfied, what a waste of money. ;(
