Actually Orayay,
It works extremely very well!
I do keep it clean with a once a month cleaning.
Just one thing though that seems to be a good addition and that is an ATO unit of some sort.
I do not have one yet but will be getting one in Aug.
You have a choice of keeping the gunk wetter or dryer. I keep mine wetter and seems to pull out more
IMO.
Are you thinking of getting one?
