I purchased the 11 piece kit. Very high quality. It is a little harder to squeeze than I thought but then I do have arthritic fingers.
I’ve only crimped the generic connectors that I already had but I have a shrink connector set from Wirefy coming in a couple of days. I think those may crimp easier as they are copper. So much better than my old crimpers.

Wish I would of found this years ago, great tool, works excellent

The tool is a keeper, but its instructions aren't--they need to be more detailed and descriptive on how to insert the dies and connectors prior to crimping.

Got mine today. Love it! The only negative think is the little storage boxes are locked in to tight. I still can't get one out to fill it without causing damage to the box.
