that price was best as I can find.
The item is truly brand new because battery management tool says it was built on Feburary 1st 2008. No long stay in warehouse.
3rd party battery might cause serious problem,I'd like to strongly recommend you taking genuine one.

This is a late review as I have been using the battery for 2 1/2 years and it still retains +/- 90% of it's original life. I'll buy another as soon as this one dies.

I ordered this as a supplement to original battery for my R51 laptop. The old one was only lasting about 2 hours; this one about 4, which allows me to use it on a long plane trip. So far, works great and price was reasonable.

the battery worked fine and I got 4 hours of time on it mostly playing a video game. I can't give it 5 stars because I have only had it for a month.
