Sumps designed for Filter Rollers (Synergy SK-Series, Geo AFR, Trigger Titanium/Platinum, etc)

I haven't had any issues. Changing out the roll is a bit fiddly. I've not found a way to attach to the take-up spindle that I like, but I've only done it 3 times.

I forget it is there most of the time. On my system, it will go through about 1% of a roll each day and I hardly ever interact with it.

Fiddling to change out when it’s only done once every 3 months sounds like a pretty good alternative. It’s nice to hear someone who’s actually using it without issues
