I had one for Xmas. As you move over from the horizontal, the weight suddenly takes over and the table flops down to its end stop. I drilled and tapped 6 holes in the end on a radius and made a "crowbar" for them, it acts as bit of a counterweight and makes setting angles much easier . Also the mounting "ears" were rubbish, not cast flat, true or thick enough. When you tightened it down to a mill table, there was 1/16" gap under one side of the nut compared to the other. I took a little off with my mill, but to get the area completely flat would have left perhaps a tab of 1/32" thick.
You get what you pay for. . .
