This tool is awesome. Very well made, not loose and flimsy. Just place, squeeze, repeat. I did a 6 inch pipe in about a minute and it fit perfectly into the next section with no issues.
It's excellent quality and did everything I needed to get my gutter downspouts up. Definitely worth it.
I like it where I do some AC ductwork connections.
Great tool, was great to make your hard pipes to fitting with another pieces
