Good welds. What more do you need
I've many years experience with Mig-Co2 but never used gassless before. I was put onto the Forney brand by a youtube reviewer and thought I'd give it a chance. It was every bit as good as he said, easy to use and leaves only a dusty slag residue which just brushes off. Gasless is really only for outside use IMO as there is a lot of smoke. Alternatively, use an airfed mask if you have to be indoors. I used the wire to build a new section of chassis for my truck and will buy more.

One of the best flux core wires.
Almost no splutter and smoke. Very clean welds. Excellent company.

Good wire
Was not sure of this wire always used another brand, but was very happy and surprised with the arc start characteristics and weld quality will use this again .

Accurate.
I found this product to be cleaner than the previous brand I was using. used for welding 40mm box with 1.5mm wall thickness.

not over impressed
Having read loads of reviews and tests, everyone seemed to rate this so I bought some.....far from being the shiny bright product I expected it was dark grey and dirty looking. Having just finished the small reel that was supplied with my Tigren 140 welder I loaded it and proceeded.....jees talk about smoke.....whereas the previous wire produced minimal smoke and spatter this was quite the opposite - and in contrast to all that I had read....it produced copious amounts of smoke, so much so that I had to keep stopping to let it clear....and yes, I am welding outside! The end result looks reasonable but the thick brown deposits and smoke stains just werent there with the original wire, unfortunately it didnt have a name on so I dont know what make it was....the original wire also produced far less spatter than this. The wire is also quite brittle - bend it in half and it snaps....not sure if thats good or bad but other wires I have used are not brittle like that It does work but I am not overly impressed edit...I believe the original wire may have been SIP 02706....considerably dearer but maybe thats why it appeared to be better

Broke straight out the packaging
As soon I took it out the plastic packaging it's burst open. The plastic of the one side has broke loose

Not vacume packed
Did not come vacume packed. Quite tarnished. Left a dark stain when wiped with a cloth. Welded OK. I would not class as a premium product even though they are charging a premium price

Best wire I have found on Amazon. Low splatter, good welds. I’ve tried others and they don’t compare.
