We were happy to test the ASUS Cobble and TUF Gaming A2: both are practical, plug and play and easy to use. The two Cobbles, in grey and black colouring, are better looking and also easier to use, they can fit in your pocket or in the smallest compartments of your backpack. While the TUF Gaming A2, has on its side a better resistance, from this point of view it is more practical and defends itself better in all conditions, even the most extreme ones.
