Makes my gutter install and repair easier
Worked fine for putting the end caps on my gutters. Nice tight crimp that holds the end caps on before I seal them with caulk. I'm a DIY guy, not a Pro. Will never wear this out. Used it on one shed project. Will use it to help family and friends fix their gutters. Worth the price to do a quality job and not have to hassle with leaks later. And cheaper than hiring out gutter work. There's something about owning and using a well made and well designed tool.

Good end cap crimp
I haven't purchased this brand before but decided to give it a try for our gutter business. Works well and seems to be good quality.

Price point perfect
This metal crimper surprised me in a good way. The joints are tight, it bites clean, and it does exactly what it’s supposed to do. For the price, you’re not going to find a better option. I wouldn’t recommend it for a full-time pro who’s using a crimper all day, every day, but for a home DIYer knocking out a gutter project, it’s perfect. Solid performance without draining the wallet.

Mutt crimps
The tool feels heavy duty and did a fine job crimping the end caps on gutter. Overall I’m happy with the purchase with the exception of they’re made in China. Great price compared to what I could buy locally.

What a handy way to attach the ends to my aluminum gutters versus the old way of adding screws and sealing. I like the clean look it has when done.
