I don’t like the larger Anchor heat shrink connectors. The barrel is too short imo and the jaws of their crimper want to slide. I use them for quick repairs. Uninsulated and heat shrink. I have a bunch of the small anchor that I will use with an endentor crimp when I don’t care if I puncture hs. Love their small terminals just not that crimper. But heck next thing you will tell me crimp, solder and HS are bad
