Pros: Light weight, that's about it.

Cons: On the first unit shipped the wireless lan control did not work. It was replaced with one that has a constant annoying buzz from the fan. Feels a bit flimsy. The shift key on the right side is tiny, should be as big as the one on the left side of the keyboard.

Overall Review: This is very inconvenient. We have been shipped (2) defective units in a row. We need this for an upcoming trip so I will have to buy another unit. It probably won't be an Asus.

Pros: none

Cons: This controller would not connect to itself and kept generating compatibility errors when trying to install the software. Tried on three different computers with three different systems (XP-SP3/Win7/Win10). The supplied CD does not run the driver software when you insert it into the drive. Waste of time and money and now I'm out the $11.95 to return this defective device. Device is not for the US market based on the package lettering.

Overall Review: Spend the money and buy from a US supplier.

Pros: New.

Cons: Took over a month to receive this battery, way too long, was shipped from Singapore.
