I have noticed that my rubber bands dont last as long as I expect them to last, they usually dont pass more tan 25 shots without being broken, or with holes even with maximum band life design!, this bands are blue and are the hardest flatbands of Decathlon, as Joerg said comercial bands can have poor quality, so do you think theraband is definitely better than decathlon's? It will be very interesting if Joerg, tested the resistence and power of different types of flatbands! or other types of bands... Are you with me? <img src="http://illiweb.com/fa/i/smiles/icon_wink.gif" alt="Wink" longdesc="15">
