I have bought myself the mumbi cable for charging my smartphone to the bicycle handlebar. The here to bridging distance is only about 20cm. When searching for a USB / Micro USB cable of this length I was not initially find. Then I came across this roll-up cable. At first I was a bit skeptical at the reasonable price especially with regard to the quality of the up / rolling function. I now have thrilled the cable three weeks and am use. The shut-off / roll-up mechanism can be locked in any desired cable length and works perfectly so far. A big advantage is also the short USB connector, since the bicycle handlebar is little space for me. So I can be switched on and disconnect the cable without problems. The 90 degree Micro-angle plug is with me in the "right direction" (to the right), so that the connected cables will not expansive and so overall very inconspicuous.
This USB Aufrollkabel is a smart idea and price and quality are right also. Therefore, like 5-stars.
