Review on 85W T-Tip Power Adapter for Mac Book Pro/Air with Retina Display, mid-2012 onwards – Replacement Charger by Jaye Cleveland

I ordered this charger and had to get a replacement because the one I received didn't work at all. The second charged me for a few days and then seemed to short out. Sometimes if I wiggle it enough and then don't touch it, I can get it into a position where my laptop is plugged in, but that's obviously unsustainable (and it seems unsafe). Unfortunately, the return window was very short, so now I just paid for the charger. Don't waste your money as it will likely break soon after you receive it. Get one from the Apple Store at Revain (it's cheaper than the store, around $50 currently).
