I find that the J. T. Eaton 421CL is preferable to the Victor. The two traps appear to be identical, except that the Eaton has a plastic 'window' in the cover that makes it much easier to see whether there are mice inside. The disadvantage of the Eaton's plastic window is that it is not very durable for outdoor use, since the plastic shatters easily once the trap is a year or two old.
