Product review (5 stars): Great product!  But be sure that your existing electrical box can handle it or plan to change the box.
I bought this and installed it and it works perfectly.  It charges Iphones, Ipods, and Ipads.  I was worried that it wouldn't charge my Ipad, but it charges no problem.  I bought the 20 amp outlet, even though I don't think that will affect the USB ports, which supposedly have 3 amps on either the 15 or the 20 amp outlet.

The one warning that I have to give with this is that you may need a new box to house the outlet if your existing box is not deep enough.  You may need this because the outlet is deep, probably because it has a transformer for the USB ports.  I was able to change out my box, but that was relatively easy because I I had access to the box from the back side of the wall (i.e., I did not need to remove the drywall).  A similar issue may occur if your existing box has the power coming infrom the top, bottom or sides.  Because this goes back farther, you may have to bring power into the box from the back because the fit may be too tight to allow the wires from the side.
