Both fitness bands came by Prime directly to the next day. Condition: perfect. However, when opening the package I met a very strong latex smell that is not significantly reduced, even after use. The smell of the tapes is really bestial, therefore only 2 stars. Healthy smells under any circumstances. The ribbons serve their purpose, but "work" I do not like them because of the strong odor. The different strengths are noticeable. However, the bands for some exercises are clearly too short. There would possibly be useful if you still similar to loops to buy in order to "extend" a bit too. Especially when curling (over her shoulders in a standing position), it is really difficult.
