    "abstract": "We comment on the recent suggestion to use a family of local uncertainty\nrelations as a standard way of quantifying entanglement in two-qubit systems.\nSome statements made on the applicability of the proposed \"measures\" are overly\noptimistic. We exemplify how these specific \"measures\" fall short, and present\na minor modification of the general theory which uses the same experimentally\ngathered information, but in a slightly different, better way.",
