I have tried multiple devices, two iphones (5S + &S) and an Ipad, device timeout, update failed, restart amplifi....this reeks of a scam....to use the amplifi remote I need to update flash memory on the amplifi, and I cannot update the flash memory...problem is I waited to recieve the printer USB, and now I cannot return the amplifi, I am basicly left with an ugly bluetooth speaker....this is truly a horrible product, I would advice everyone NOT TO BUY THIS
