Recently purchased crimpers for uninsulated closed barrel terminal ends . For being of Chinese manufacture they are high quality and perform well ! There is an adjusting sprocket to increase or decrease crimp tension . Some crimpers have a screw to hold jaws in place , some have magnets .
Would like to see a crimp done along with a pull test for this to be considered a product review. This video tells me little about their profomance. I've already gotten bad connectors from amazon. So don't I don't trust their reviews anymore.
