Have ordered two times directly, because I regularly lose my jam bands anywhere. Basically you get what you pay for. These simple jam bands are certainly not the highest quality but they serve their purpose, do not break the first time and work even after they have stayed once in the Desilösung (had forgotten it there) How do I can not say long it holds and I use it is not every day several times. but occasionally on the RTW perfectly fine. Delivery a bit longer but it also free and at about 2.30 euros a piece I am angry not so much when the next one is indeed gone;)
