OK so I bit the bullet and ordered a Soap Reactor for the Mark III. It couldn't have come a better time too, when I was removing the batteries last night I already found that one of the contacts for the chest shows corrosion, so I was glad to finally ditch the alkalines.
Quality is on point, I didn't have a problem with any of the cables or unit. I'm really impressed with the range of the remote, one quick swipe in the air and the lights turn on/off even from across the room with the power supply hidden from view. The wires are thin but fairly strong, and rout under the battery covers nicely. The only issue I had was fitting the AA battery adapter in the base, the (+) nose didn't touch the contact so I inserted a small piece of foil to create the circuit. The hub has enough ports to power two Iron Man figures.
