Sure your right, our guy swore by them. He had a set of spanners that were more like ring spanners but had a ratchet inside the ring, so if you can get over the nut little movements did/undid. Always thought they didnt look strong enough to put the right torque on, but must have done the job. Others were angled to get at difficult nuts, not like my big, old, open ended spanners.
