We use these to keep all our 10m XLR cables on which means no more knots when rigging cables at the next session! Storing XLRs serially on a drum means they can all be tested in one go.
The flange on the front of the drum allows the other inside cable to be fastened securely, along with the velcro strap which is a nice touch (and doesn't come with the smaller 235 drum). If you want it to be really smart you could hardwire a short XLR to a face plate but that means the drum can't be used for other cables in the future.
The drum is lightweight but strong and German-made. There are two holes on the inside, one small with a rubber valve, the other much larger if you're adding a loom. Again the larger hole is missing on the smaller 235 drum.
The cavity in the middle is kind of gaping when you first look at the drum which provides minimal protection to internal cabling so perhaps a face plate should be included by default, but in practice this doesn't matter if storing standalone cables on the drum.
