The manufacturing tolerances of this splitter aren't up to US standards. The unit arrived with a snapped off bolt loose in the packaging. The reason it broke was that during the manufacturing of the handle(s) and the frame assembly the hole on one handle for said bolt didn't line up with the hole in the frame. This forced the worker to angle the bolt through and in tightening the nylock nut the bolt was stressed sideways, thus setting the stage for the rough handling in transit (the package arrived almost completely wrapped in clear packing tape) to snap the bolt in two . Using the hole in the tubing of the handle as a guide I drilled through the frame in the correct position and replaced the bolt/nylock nut with stainless parts. Also, the wheel assembly area is very flimsy and was (easily) bent resulting in the unit needing some adjustment to stand steady in the upright (storage) position. The wheels wobble greatly on the axles, so one needs to be careful wheeling the thing about, especially on uneven surfaces.
Functionally, the unit performs as expected for a 7 ton splitter. The two handed operation safety feature necessitates some acrobatics to hold an out of perfectly round log in place with the right hand while using one's left hand to hold down the motor activation switch and one's left knee to depress the ram activation lever until the ram contacts the log enough to stabilize it.
With steady usage it appears as though the hydraulic fluid may thin out as it heats up, causing the unit to stall out on larger length logs more easily. Letting the unit stand for a while seemed to mitigate the problem. Also, I was splitting recently cut live maple wood which was harder to split by far than some dry logs I had. The splitter actually did well in my estimation.
All in all, this splitter performs as well as can be expected for its size and cost.
