If this charging stand had a rocker switch to change from charging mode to dock passthrough mode, I’d be more than willing to pay $30 for that.. but if you can get ahold of one of these for $10, or with an official charger for $35 or less, go for it. At the price that this is, it just feels like a ripoff.
