Which reminds me of this offer came just right. I've made my decision with 50cm length of the three cables. This fits very long very well, that you can invite three devices without getting in the way (the 20-cm-cable would have been too short for me). The perceived quality is reassuring, and all devices that were previously connected have downloaded, what's not working properly at any USB cable, as I unfortunately have often realized.
I am very happy and give it 5 stars.
