This time it worked as expected.

It works.

Having tried other models by other manufacturers, I can tell you that "it works" is a big deal. Because some work, then fail, and some just don't work at all, and you lose your shipping costs to and from Hong Kong...

This model, this brand - it works. Mine has been in service for a good long while now, and no troubles.

I was lucky to have gotten a warranty from these guys.  Though I didn't expect to have trouble from my computer, I did and they were right there.  Thanks!
