I got this for my 5 year old. I loved the concept, unfortunatley I never seen such a flimsy toy. We had to super glue everything together because pieces would fall off, this is because there are no snaps to keep levels in place but rather just fits together. Would not buy this toy!!!!!!!!!!! Would not recommend this toy unless your willing to super glue all parts!

Naader was my first yoga teacher. When we moved out of state, this video was my link to the best yoga routine I have ever done. I tried other instructors and other videos, but Naader's approach is the best -- a balanced mix of yoga instruction and inspiration. I have shared this tape with many friends (who then bought their own copy!) and they all agree that Naader's instructions are easy to follow and the pace is slow enough that beginners can figure out what is going on before the next pose; but not so slow that experienced students get bored. Furthermore, since he is doing the poses along with the student, he knows just when to offer that extra word of encouragement when you are about to give up! I find something new to ponder each time I listen to this tape. Naader's words are from the heart and they reach out to touch your heart as well as your body. Buy this tape and use it!!
