Query: Hi Capacity 90 Watt AC Adapter

I thought that I would try purchasing a cheaper product for my Dell Inspiron laptop other than the battery supplied from Dell since the customer reviews and ratings on that product were horrible..... big mistake. This knock-off didn't even last a month and I still paid $50 for it. I have to contort and move the wire countless times and directions in order for it to work (maybe.) I would not suggest this product to anyone and my solution to this ridiculous battery problem was to purchase a mac :)Now I couldn't be happier.
