Those grinders are not very strong. For someone who doesn't do much with it you will be fine. The bearings are weak and the bodies flex. Chech to see how much the collet is off-center before you do much with it. Treat it nice and it might be fine but if you try to do too much or do it too fast you are going to be reminded why it says, "Wear safety glasses when using". It might be a good idea to get a good pair of heavy leather gloves to wear while you are using it.
