Robust construction, excellent fit and finish. If you need a first stage seamer, this is the one. Great customer service from Stortz, too!

I received my seamer today and with a flashlight and ladder in the dark went out and tried it on my woodshed roof and WOW, problem solved that I thought I could do with vice-grips and a hammer and dolly. Great tool. Thanks for the prompt shipping and delivery.
