The charger was delivered across the country overnight by USPS Express Mail (I paid extra because I needed it in a hurry.) Advertised as 160% more powerful than OEM, it is 2x as large physically but doesn't really impede anything. It actually makes the base a little more stable since it stands out from the back of the laptop. So far, I've drained and recharged it only once (it came with about a 70% charge) and seems to be holding power pretty well. I'm completely satisfied with the product, the price, and so far, the service.
