I recommend this product
Tool consists of two parts - the big "ring spanner" for the bottom bracket itself, and the little plastic splined knob that plugs into the end of the crank.

The spanner is straightforward and fits directly on some of these bottom bracket bearings, like the SM-BB51 that I was taking off the bike. My replacement BB-XT800 is a smaller diameter, but included with the bearing was a plastic reducer that clips into the tool and allows it to be used on the smaller bearing. Would be a problem if you were buying the tool just to do maintenance on one of these newer bearings rather than replacement and so don't have the reducer.

The plastic knob for the crank end bolt didn't fit perfectly on my cranks (the actual mating part is fine, but due to the shape of the crank it wouldn't sit squarely). Would be nice if it were a bit longer. However, it was good enough to get the job done as this normally needs only finger-tightness.
