This device is what I wanted, but I had some problems: it broke down so I sent in for repair acer and he was returned a device other than mine. It took me to make myself the steps to retrieve it. I noticed that the battery no longer held the load was not the original one. I contacted acer who did not want to know. Since it has become quite unstable at Acer are several letters remained unanswered. Despite this I can use less correctly. Conclusion: this will be my last purchase Acer.
