Let’s start with Weight; the grinder does not weigh a ton, which isn’t very pleasant when you have to move it around your shop. Next cause of it construction you need to be careful when you secure it to a grinding stand or a bench. The base is made of aluminum so you cannot tighten it as much as you can a cast-iron base. However, because of the balance of this particular machine, you don’t need to do that. I said it on my standard workbench and started it to make sure that it ran. It didn’t move an inch even on a dust covered bench. It was easy to assemble and change out the grinding wheels for the diamond wheels that I have for my lathe tools. The grinder size is just right for my shop and what I’m doing with my chisels. The grinder starts nice and slow and seem to have plenty of power once it gets up to speed. The durability will come in a lighter day due to the fact that I haven’t done anything other than set it up overall I would give this a good solid five star rating for what I’ve basically checked. the question I always ask what I buy another one from this company so far the answer to that is yes.
