Some of wich are going on 5yrs. now.
IMO. you can always go "bigger better stronger" on your filteration; sump,canister,wet/dry ect.....
HOF seem to be easier for most people to maint....in a timely manner,unlike the other options.
Bottom line, it's a easy filter to use that works well.
theres people here who have used them for 15yrs+

gotta love having extra filters
