The battery works perfectly but independence still remains very limited. By setting minimum brightness, wireless off, without her, I can make it hold for an hour and a half in office mode as it is to type reports in Word, which is still low enough to a battery, I expected better and was hoping at least 2 hours early in the life of the battery. That said, the price is still very correct and fast delivery and well packaged.
Edit: after my first comment, noted 2 stars, the company contacted me to offered me an exchange. I admit to being very pleasantly surprised. The new battery seems to work great, and congratulations for Customer Service.
