Unfortunately I missed The return

Not worth returning

n’t work at all

It works by powering to all ports; but DON’T touch ANY of the individual ‘power’ buttons as this wreaks havoc and is nothing more than a worthless gimmick

n’t had mine long but works fantastically.

n’t clear that you have to push a button by each port you want to work

n’t lose the connection while still getting the benefits of spending extra $$ to get an ergonomic keyboard.

n’t have concerns about it breaking any time soon.
