for fast delivery, immediately in my notebook. Fits right, no Probleme.Verpackung was great. Compared to the previous speakers, I have to say that the battery lasts not so long with me, as listed there partially. At half the activity on the notebook, he sit by Kaun 2 hours late. I have charged him as described and so far 6 times fully depleted and recharged. It is better not yet become. Why only 4 stars. But otherwise highly recommended.
