This is a hit for our 3-year old. The flashcards and letters are sturdy and colourful. The set keeps my daughter engaged and challenges her at the same time. So far she has been using it as a puzzle and to match sounds, but I'm looking forward to her doing some tracing/writing practice with it as well. Such a versatile resource that not only makes learning the alphabet and sounds fun, but also develops other skills such as problem solving and fine motor. We are very happy with it and would highly recommend it.
