I broke my original ASUS adapter while abroad (the LAST place anyone wants to have laptop issues!!), I bought this adapter to replace it. I've had it for about 2 weeks now, and while it works perfectly well, the only main qualm I have is that the length of the actual cord itself is a bit short. It's not a problem when I'm charging my laptop at home, but it does make it a bit inconvenient when I'm in public places (libraries, coffee shops) and want to charge my laptop. Also, unlike the original adapter, the actual apparatus plugs into the outlet horizontally (the ASUS adapter "box" part is vertical).
