Good crimpers
Great crimpers and seem well made. Easy to use and I think they'll last a long time. Would recommend and would buy them again.

Quality tool and worked well.
Used these crimpers to shrink one duct to fit into another. This tool worked better than others I've used. Very happy with the purchase

It works well and is well constructed. I would like another 3/8" to 1/2" of crimp depth though.

My old crimpers broke so I thought I would try this brand. They work but the hand grip is uncomfortable. Could be just me.
