I've done a fair amount of wiring in my time, and I've used many different crimpers.While this is by no means the best I've used, it is certainly better than any other crimper I've seen for less than $40.You wouldn't want to buy this if you're making cables every day, but for (re)wiring your house and making some patch cables every now and then, this is a great tool and the quality is excellent for the price.
