Ok, got some pics, it looks pretty clean.
The pcb is Atten branded.
Few issues, live and neutral are both blue. Earth goes straight to the pcb and so the bottom half of the chassis is earthed only via the screw holding the pcb to the base.
The housing of the tranny measures about 23ohms to the earth pin and the top cover is as good as open circuit (not earthed).
The tip of the wand measures about 6ohms to earth.
I switched it on anyway after putting it back together and it works really well.
Mounted some RGB pixels with leaded solder paste and the atten set to 220 degrees.

Did OP post the link of where he bought it from? If not, he should so that more people don't buy it from there.

Here's the photos I took, I'm not sure if Tapatalk will make them too small to be useful but the forum wouldn't accept the gargantuan photos from my Xperia Z.

Beware of the IEC lead it came with. Fake as hell.

Thanks for the heads up, what issues am I likely to suffer with it being fake? And should I just bin it and replace it immediately? I have spares lying round al over the place.
I used it last night for my first attempt of removing components as opposed to placing them. I tried removing a few components from an old HDD board, couldn't remove any of the TQFP with it set to 400 degrees. Managed to remove plenty of 8PDIP and SMD resistors etc. I think I had too small of a nozzle attached for the TQFP. I'll be a bit more agressive in my next attempt.
I'm still not sure what temperatures I should use. At 220 I can easily solder new components with my lead solder paste, but desoldering the board from a WD HDD wouldn't budge at 22, or 280.
