Did you take this apart and look at the construction?
The folks questioning the connector are spot on.
Failure rate on this deck is high, and will get higher as ALL will eventually fail, unless you tuck 'em back in the box and leave them there.
The way the unsupported usb cable hangs out the back means that the slightest tap will cause the cable to lever up the connector, and eventually the two tiny fingers of the connector will part ways with the pcb, resulting in first an intermittent connection, then a dead keyboard.
Not maybe.
Not might.
Will eventually.
To add insult to injury, when you do open it to repair it, you'll see most of the solder joints have the dull look of a cold solder joint.
Having repaired this one, it works fine.
Now I need to bring my deck in from home - the one with the led that's been dead from day one - and see if I can fix it.
Let me add that your review is a fail as well.
The specs are straight copy/paste from Rosewill, and I recognize some other verbiage from one of the keyboard geek sites.
Shame on you for being lazy and misinforming your readers.
