We ordered this for our daughter (age 7) to do her schoolwork.  She only uses it to complete assignments daily and keeps it in a backpack when not working on it.  The battery has completely failed after less than 6 months of use.  This was not plugged in all the time, but only plugged when the battery strength was low.  Very disappointing that this lasted less than 6 months.  Will not buy again nor will we purchase another product from the seller.
