Sometimes you just need a good dry erase board to keep a running list of all the things you have already forgotten as you walked into the room. This board isn’t going help you remember anything if you don’t remember to write it down and it is too big to carry stylishly. The eraser on the little pen it comes with is really meh, but the board erases easily with a tissue, the side of your hand, your shirt, or any small fluffy thing you have handy. However for your safety, I do not recommend trying to use a cat or a dog as your eraser because they will scratch and bite. Worse still, they will judge your ideas and any secrets you put on the board.
