The grinding stand is solid enough for occasional work. All supporting parts are made of steel. However, some screws, the return spring and especially the small machine vice may have somewhat frail. The price can get over this, however. With a good angle to ensure that all scheduled work done quickly. That would be for me four star. For heavy duty applications, but I do not recommend the device. A deduction on three stars there that the angle can be clamped only a hassle. You have to solve four screws to secure the grinder at its two handle threads. Then you have to adjust and fix in order to make halfway right-angled cuts can angle with two more screws. In total, six fixing screws are to "serve." As you think about it twice before incorporating the angle or rather not take a hacksaw.
