Unfortunately this base station does not live up to its promises. You still have to perfectly place your phone to get a charge, unless you want to position it horizontally and take up 2 charging coils to get it right. I returned it.
Since I can't edit my comment, I'll correct it here. As others have pointed out, I bought and returned the "Base Station" because it only had 2 coils and needed precise placement. I have not used the "Base Station Pro" (but will give it a shot, since it has some advanced tech). I jumped the gun on my comment, so the above comment is not accurate.
if you want the one thing that will work, though with a much less polished very un-Apple-y design, this is expensive, huge, and it will work basically edge to edge.
I will say having used it, I understand why Apple axed the idea. It is huge and gets hot and I assume it is thicker than Airpower would have been.
