Thank goodness this product was invented...I don't know what I'd do without it!! My 3 yr. old INSISTS on doing her "artwork" on the walls (no matter how much PAPER I give her!) , and this magic eraser takes it right off...I don't even have to scrub...it just wipes of so easily! I use this on EVERYTHING....walls, appliances, counter tops..etc. I LOVE this product!! =)
