I ordered this product to recover after losing everything during the Almed arson in southern Oregon. I'm looking forward to getting it as I've moved and have an insane amount of work to do in my new home. I was glad when the grinder arrived but I can't use the damn thing as it obviously doesn't come with a wrench. for loosening and tightening the washers on it. There is no key, I tore open the box and looked through the whole package. no key. How the hell am I supposed to use it without a piece that allows it to be attached and detached? This is a first for me as I have never had a keyless grinder to loosen the nut so the disc or pad can be attached. So I assumed that I would have to order a wrench separately and wait for it to arrive, which means the work here has to wait a lot longer. So I can't even write about how the grinder works and what the pros and cons are, if any, as I can't even attach discs or pads to it. Good. Big. The only positive thing I can mention is that the delivery was on time and the discs for the grinder that I ordered arrived at the same time as the grinder.
