Let me start out by saying that I was quite skeptical of buying a battery online for half the price that Asus offers them at, but being the extremely broke college student that I am, I really didn't have much of a choice. Let me tell you that so far, this product is great. (its only been a few days, but all seems well) Fits perfectly into my laptop, and holds a charge for over 3 hrs while surfing the internet and through constant use. I would suggest your site to anyone and am extremely satisfied.
