We analyze, within a dipole model, the final, inclusive HERA DIS cross section data in the low $x$ region, using fully correlated errors. We show that these highest precision data are very well described within the dipole model framework starting from $Q^2$ values of $3.5{\mathrm{GeV}}^2$ to the highest values of $Q^2=250{\mathrm{GeV}}^2$. To analyze the saturation effects we evaluated the data including also the very low $0.35<Q^2{\mathrm{GeV}}^2$ region. The fits including this region show a preference of the saturation ansatz.
