This easel is my grandson's favourite "go to" toy when he's in his playroom. He has every imaginable toy, book, electronic device, etc. and yet he always chooses the easel. He never tires of manipulating the magnetic letters/numbers to create. At 2 1/2 he can already read and recognizes numbers greater than 100. If there is any criticism, it's the limited numbers of characters. I've ordered 2 more sets and the problem is solved. If I could make one more suggestion, it would be to include lower case letters. The easel will continue to grow in use along with my grandson.
