Regretfully, I bought a 45mm cutter from them, just before your second post. I haven't even taken it out of the packet.
One of the side spurs is missing, due to a fault in the original casting, the central tip is a thick, square lump that might have come to a point if it had been a few mm longer and there are burrs raised on the rim cutters that are easily 2mm to 3mm long and as ragged as Bob Geldorf's stubble.
It's going back!
