I live in Korea and recently bought the starter set + wand. It's a total game changer. My daughter, who previously was not super interested in practicing Korean, all of a sudden can't wait to read and repeat after the wand. I can't wait to order more books. Highly, highly recommend!
My twins love these books and wands. Not only is it helping them with their language skills it has helped them practice their reading as well. We use these daily! My children also love the feeling of independence that they can practice without me as well!
My only complaint is that we want MORE! These books are great for vocabulary acquisition for my young son. With engaging illustrations and the wand, he loves to go through them. What I would like to see (and maybe there are books like this in other languages, we are just using French) is a few more narrative oriented books as well. Nothing helps people learn like stories!
A great toy/tool for our son who is in an immersion program at school, but needs more comprehensible input at home. Easy to charge, easy for him to use on his own (he just turned four).
