Even if this one lasts for the same ammount of time, it still cost me LESS THAN HALF of what an original Dell battery would have cost...
As far as I'm concerned, I would recommend this product to anyone who owns a Dell and donesn't want to get ripped off buying $300 battery that will only last a year, maybe even less.
