Very expensive to fix? Of course a complete wet side, dry side, controller are not inexpensive. But at least you have that option with a VorTech. In my experience running MP40s for 5 years +, the parts that typically wear are on the wet side. Repair kits, ceramic bearings are a bargain. Not sure any other manufacturer offers the same options. Once a Jebao is done, it's all done, trash.

Comparing exotic cars to water pumps is a bit of a stretch, no? If I were able to go back & choose again based on what I know now, I'd buy another. Folks who like their Jebaos are free to do the same, based on their experience.
