I used this to make screen covers for vents under the house and in the attic. The screen I used was 1/8" gaps and stainless steel. I had no problem making all the bends and they look professional. Approximate size of rough blanks were 7" × 17".

Will bend sheet metal nicely

Made very good

Build quality: I've seen much worse out of China, but it shares some of the annoyances - the threaded connectors for the bending handles are welded on nuts. So the strength of the connection depends on the weld. The track is cut completely through the back. The bending leaf is not totally flat /parallel unless you press down on the handles. It's off by about 3/32nds. Not that that will effect the bend, but it's worth a mention (last photo.) The nuts were painted after welding - and the inside threads were almost solid with paint. I needed to use channel locks to thread in the bending leaf handles and break the paint free. The plastic grip covers on these handles wind up at odd angles - one had the finger ridges pointing up, another sideways. I'm thinking of removing the plastic covers and using padded tape instead. The teeth can be combined and moved around, so if you have a couple of sizes you often use, chances are you can set up more than one size and leave them - you have room to work with. The base can be bolted or clamped - there's a large enough lip on the base. I'd say it's a solid 4 stars.
