Query: *** DANGEROUS *** SHOCK HAZARD ***

I purchased six of these at $5.99 each from amazon. At first I was in love with them. I put them in the kitchen and the bathrooms. They make great night lights and you add outlets. What could be better? Safety could.So far TWO have shorted out violently resulting in spitting of sparks, charing of the appliance plug and blowing the circuits at the circuit breaker panel (different appliances, different circuits, same results). Ground faults seem to be a common manufacturing fault with them. I have just ordered a ground fault tester to test the remaining four but they will likely be going back to amazon or the trash. Seems to be a case of typical cheap Chinese production.
