Due to a therapy had and I wanted to also buy myself an exercise ball. All previous models (also similar. Price range) showed weaknesses, shortcomings and mistakes, also were sämtl. Copies always to many centimeters smaller than described. My physical therapist, I lamented my sorrow, advised me Pezzi, because it has these balls for over 9 years in their practice and has never had complaints or problems with it. Then I told her about the reviews, is where written repeatedly of the odors .... and the discouraged me from buying. She could not quite understand, because every new piece, be it a football, new shoes or a techn. Device happens to have a "new own fragrance," but it really is very limited at Pezzi. Ordered and yippie So ball !!! finally holding this ball, what it promises. Namely full 65cm !!! The odor is also much lower than expected and also lower than some previous models from other manufacturers. Pezzi seems to be a little more stable and robust, what a therapist while. Exercising is a greater sense of security. I can only find a negative aspect, namely, that I experimented around as long and handle is not equal to the right ball to Pezzi .... REALLY spotty smells !!!! PS The fragrance is rather slightly sweet, vanilla-like, as the classic "rubber smell", so perhaps a little irritating.
