The Koro has a good design and they function quite well. That being said they are a very limited production trap and therefore are much more costly than the materials would indicate. Most Koros are used in Europe and some are used here in the US of A by adc persons.
Buy yourself one or two and test them out yourself. Look for situtations to use them. Remember, they are yoke type killer traps and require baiting. However when you get a load of the price you give up any ideas of outfitting yourself with a line of these traps as a bad job.
