Our take
The best thing about the Magister 4 in × 30 in Cylinder is a 4 in bore, 30 in stroke. No buyer reviews yet, so this Magister hydraulic cylinder has to win you over on paper. The catch with the Magister: no word on the exact fit. We'd pick it if you are rebuilding or building a splitter; otherwise, put it next to the AMRAP 5 × 30 in Splitter Cylinder first.

Your splitter's manual names the oil grade, the part numbers and the sizes. Match them before you match the price.

Only if its stated dimensions and compatibility match your exact machine. Check the model list, tonnage, beam or wedge size, ports and thread sizes against the listing and your splitter manual; a shared brand name or a similar photo does not prove a fit.
