I bought a couple of these on amazon, and whether the concerns about long term use are valid or not I do not know, however like my pre-order I am betting that they can at-least handle the load for 3-4 months and I will be inspecting them daily so, its an acceptable risk for me... Time will tell however.

These are simple devices and I'd imagine the bulk of the load is simulated over a resistor or a transistor based current limiting circuit, which usually fail open if they fail at all. I might open one up and inspect one to be sure. If I do, ill let you know what I find and possibly post some pictures for analysis.
