I never write reviews, but this one is worth it.
I bought this since it was decently expensive compared to some others and was the same brand as an old one my church has that works just fine. This one is junk though. My 2 year old hates it. It writes fine, but you have to go over the board 5 or 6 times to get it 'cleared', and even then it leaves a heavy residue. It frustrates him enough to where he doesn't play with it. Maybe it'd be fine if he weren't used to the 'good' one where you slide it once and it erases in one swipe like we had in the good ol' days.
Luckily we paid less than half price for it on Black Friday. Don't waste your money on it though. We're looking for a better one.
