We present the two longest (to date) general-relativistic simulations of equal-mass binary neutron stars with different compactnesses, C=0.12 and C=0.14, and compare them with a tidal extension of the effective-one-body (EOB)model. The typical numerical phasing errors over the $\\simeq 22$ GW cycles are $\\Delta \\phi\\simeq \\pm 0.24$ rad.
