I use this product from last two months.You buy for this product for fingerprint scanner and excellent battery backup.Only pre installation windows is not there.
The Asus R542UQ-DM164 is a stylish laptop the out standing configuration delivers a powerful performance while handling multitasking.The battery backup is good for daily usage.The laptop RAM can be extended upto 24 GB.Overall the Asus R542UQ is worthier one around this price tag.
