Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I usually avoid 3rd-party batteries, since they have a rather notorious track record. For my wife's Studio 1535 laptop though, $100+ for a Dell replacement was too much for an 8 year old laptop, so I decided to just look around and see what I could find. So far, this has been working great, and definitely more battery life than the original battery ( which was the standard size, not extended ). Hopefully this won't explode sometime, but for now it has made her laptop portable again, and thus is worthy of a recommendation.
