I have a macerator I use to dump at home 80 ft away uphill a few ft.
For this it works fine.
I never use it if I can use a 3" hose. Here's why. It dumps much slower than a 3" so you have to rinse many more times to get the tank clean.
They wear out and and or jam so you have to take them apart every few years to replace the impeller and clean hair off the shaft.
If a kid or a woman puts anything other than body waste in the toilet, it will jam, leaving you with a couple gallons of raw sewage to deal with.
