Does exactly what it's supposed to.
Yes , I recommend this product
Does what it's supposed to. Worked perfectly for removal + install of Rotor BSA30 bottom brackets, as promised in the description. Cams off far far less than Rotor's own version of the tool (not zero, but waaayyy less, probably as it's deeper) and I doubt it'd ever wear out as Rotor's does after 2 or 3 uses. Good quality. Could be nice if the sharp edges were rounded off a little so as to scratch less.
