Overall, the quality is superb, as with all other strength shop products. I made the mistake of getting the 10KG one as a mace-novice. Although I consider myself to be a strong guy, I did not expect how much leverage means on a handle of that length. To everyone wondering if you are strong enough for a certain weight, probably a good idea to go down a size or two :D
Speaking of long handle, another thing I didn't consider when buying: If you are on the taller side, this thing is *not* for indoor training. Unless your ceiling is ridiculously high, you will hit it sooner or later doing e.g. 360s. So if you don't want to startle your upstairs neighbors, either get one of the non-competition maces on sale here, or get used to take it outside.
