My 3 year old has every single Buzz toy there is, I think.  These new wings, purchased as an addition to his Halloween costume, is likely the best yet, although it does annoy him that he can't lower his wings down.  The inflation is good and stays for days, but it is a safety hazzard as my son walks all over the house and turns and then knocks stuff over!  Thank goodness they are just made of plastic.  The only complaint I have is that I wish the back part didn't inflate as much (it sticks really far off his body and makes it impossible to sit with it on) and wish more air went into the wings so they stayed upright better.  The purple part of the wings gets no air or inflation, only the red and white striped part and the ends.  I hope these wings last a long time because my son wants to wear them all day every day, but at least they are a good price if I need to order a new set.
