I have now for about 2 years continuous battery changing times meant in a cost-effective and environmentally friendly solution to upgrade. The Venom battery packs are stung my eye. The delivery was accustomed quickly, the packaging well. Now, however, the product, which is self explanatory, even without instructions. Simple USB plug into the Xbox and put the battery pack to the other side. The charging status is indicated by flashing (-charging) or a solid green shining light (fully charged). The battery has a day after 1 week only 1 of 3 strokes lost at use of about 1 hour. The performance is therefore fully ok! I recommend the product further in any case!
