If your not bothered about about looks and are getting your cables out of the way for airflow rather than aesthetics, then it's actually quite good. However if you're bothered about what it looks like it's not so great. It permits you to route certain longer cables out of the way in places cable ties don't. Just an alternative suggestion.
I'm just thinking of trying to get a roll around some wires in a tight space. But, you know, if you wrapped the whole set, all the way, it would actually look pretty cool. Not the easiest thing to do, but, you could.
There are velcro cable ties if you want to reuse them again and againd.
Their are "tear away" ties if you want to use them once and later easily rip them off for temporary setup and breakdown.
You can also use stainless steel ties if you need it last a long time outdoors.
You can all of these cable ties at Buy Cable Ties. I bought some tear away zip ties for hanging up my Christmas Lights on my long chan link fence. I went out this morning and popped them all off real easily.
