i got one about a year ago now.
I run 0.8 fe and a little s/s 0.8.
I'de be hard pushed to say anything bad about it, you just set type and thickness and away you go.
I found it awkward to keep the gas bottle and plant together as the lead is short, so I copied the design of trolly they sell for it.
No bother now, its a fantastic bit of kit, not that I do an awaful lot of mig welding.
I've got one too but only used it for 30minutes tried it on
2mm stainless (spot on ). Put a few inches using mild steel today flat out!! again spot on. I'd recommend them.
