Due his quiet big size it's perfect to store very long cables or even multiple cables (if same cable/plug).
I used them to store are multiple 15m+ xlr cables without any problem.
The drum is very easy in use and rolls up very smoothly.
I also love the little roll up part at the side, it makes rolling up the first cable much easier.
After trying one , a immediately bought 5 more. I regret not buying one of those much earlier. Could have gain us so much time in the past.
For this price you really will never regret buying one of this, believe me.
