This is easily one of the nicest tools in my kit in terms of quality. Biggest downside is that you can’t quite reach 90 degrees with this tool. The top bearing is at a perfect 90 degrees to the tool so once you’re maxed out you will scratch your workpiece and the spring-back leaves your bend less than 90. Not a problem for standing seams except for dialing in the two smaller bends on the female bend- since the rollers will be in contact with the leg of your previous bend instead of the rigid bend itself, any variation in pressure will flex the leg and alter the depth of your bend. This can start to get away from you especially on longer bends. Also you’ll have to get the hang of using the integrated ruler, as a single bend will need a little more than your target measurement and for a compound bend you’ll also need to compensate for your previous bend not being 90 degrees thus holding the tool further away from your workpiece…
