Functional, well fulfilled its role

The article is nickel, nothing wrong, then my bill is due to price
just a low branded items "microsoft", because we are always obliged
take that mark for the goods of the same range (eg Xbox)
to be sure of 100% compatibility.

Otherwise, nothing to add, except that the life of the batteries is greatly exaggerated
because it is not "playing 40 hours" that is available when the full battery, but
much less contrary to what is written on the box, such fifteen
Maximum hour. So either the battery has a catch, there is exaggerated marketing by
Microsoft, for I have had 2 batteries like this, and it never lasted 40 hours
game. Otherwise it is.
