What exactly looks "horrid"? Looks like a fairly standard professional circuit, with plenty of good insulation...

Tape.

Tape is a sign of bad design that can be seen a mile away. The cans on the caps underneath are being kept away from the board with tape.

That and the bare lead WTF in it.

That and it's that retarded and dangerous 2-pin design (no ground/earth) that people in the US rely on.

Well, the neutral wire is connected to earth. Grounding is important for metal cases, but when your case is an insulator (plastic), it's less important. If the hot wire comes loose and touches the plastic case, it's not going to harm you, which is what grounding protects against.

I don't see any tape. This looks like some insulating goo material.
