Plugged in to my old desktop that I use for eBay. Green lights behind buttons work. I am Unable to fully test any farther.

There are some weird hard to get off particles of some kind in various spots, the plastic and surfaces you touch are also slightly sticky for some reason. I think this happens with aging plastic or rubber. I did a little bit of cleaning with this item, but will definitely need some more.
