Bought at gadget show. Love it... great item. Buyers note other reviewer could have returned thru Amazon. This is a creative and fun tool used to communicate... make notes... keep kids busy. Was told that battery should last 8 years but if any problem that they stand behind product and will replace. Spoke to sr company rep who was really concerned about review above and said he cannot help a purchaser who doesnt contact them. Although batteries are long life things do happen and they will stand behind their product. Very happy with my slate!!!
