Query: Shoddy design

I purchased five of these power strips for the office, thinking that any 12-port power strip would be just like the others we have here. Each and every one of them is in danger of falling to pieces, the outlets themselves are constantly coming loose exposing bare wiring and touching the metal frame. On more than one occasion the internal wiring to an outlet has touched the metal frame, making the frame live and tripping the circuit breakers at the offices. Once we even thought we had toasted an expensive Mac Book Pro. Stay clear of this particular brand. It sucks. There are better ones out there for the same price.
