We LOVE the Spinny Speller!!! Amy from Let's Explore sent O a Spinny Speller as a "big sister" gift, and we "play" with it everyday. We leave it on our kitchen table and have fun making real and nonsense words during our meals. O has become VERY interested in sounded out words since we've had the spinny speller, and I've heard her on many occasions trying to sound out words that she sees around our house.
The Spinny Speller is 5 inches long and is made of hardwood. It has 3 four sided blocks that can be used to make 3 dozen "real" words and countless "nonsense" words :)
