I use a long-life bag in it and it works nicely, it isn't that messy to empty in case you have a deep can (and in case I had really find dust in it: I simply vacuum it with my shop vac after afterwards to get rid of the rest).
Saves a lot on bags, especially with the TS and when routing (and cleaning up afterwards), an OF will fill the small bag quite quickly.
Only downside of the CTL-SYS is that on manual mode the socket goes dead, so one has to decide to either use the vacuum stuff or using a machine attached to the socket. Sadly both in parallel isn't possible, so using the drilling dust nozzle with a corded drill leads to the drill needing another socket
