  We study lattice QCD at non-vanishing chemical potential using the complex
Langevin equation. We compare the results with multi-parameter reweighting both
from $\mu=0$ and phase quenched ensembles. We find a good agreement for lattice
spacings below $\approx$0.15 fm. On coarser lattices the complex Langevin
approach breaks down. Four flavors of staggered fermions are used on $N_t=4, 6$
and 8 lattices. For one ensemble we also use two flavors to investigate the
effects of rooting.
