I've had a completely different experience with the Super Split than you have. Only replaced a couple of bearings.Hydraulic splitters are pretty hands free maintenance wise. Put gas in them, change the engine oil once or twice a year, throw a tarp over them till the next time you need it.
That's just not my experience with a kinetic splitter. Once you get your head around the general fidgetting with them, your good to go.
The bearing, cam roller, whatever...needs constant attention, cleaned, lubbed, taken off and unfroze, etc. Only takes a minute or five, then back splitting.
But I've only split 70-80 cords in 7 years and the splitter stays in a shed when not used.
