Ex Input:
I bought this for a very low price, but still more than it was worth. Sure, when I got it, it worked well. It was fast, it had Google Chrome, it had long battery life, but very soon into buying it, we discovered that the power cord wasn't working, and that the battery needed to be replaced. This all cot about $70, added to the already $84.49. It would've been more productive to buy a more expensive new one. Then, later on into having it, but still not even a year, I discovered it had a virus that it had had for longer than I'd owned it. I am unsure whether the seller was aware of this, but either way, in retrospect, I would not have purchased this laptop if I'd known how much money it would cost me-past the initial purchase.
