T-Rex Fuel Tank Chameleon

I got the T-Rex as to reduce induced noise and to simplyfie wiring for my pedals.
Simplyfie the wiring it did !
But the T-Rex unit itself is bloody noisy.
Even without load it hums like an angry wasp.
Clearly a cheap and bad transformer that also lacks mechanical vibration-isolation from the metal-chassis.
I've testet it with a "clean" powersource (for sensitive IT-equipment) and it hums no matter what.
Piece of overprized crap !
Oh, and that blue LED is totally blinding.
