Good question. The difference between the two brands we carry, is that the Victor is made in the US and is of very high quality using the materials. The cheaper version are made in China and are made more cheaply. If you want a trap that can be used for a lifetime of trapline trapping, invest in the Victor traps. If you have a nuisance animal once every couple of years the cheaper trap will work just fine.
