After the battery of my Logitech diNovo Edge Bluetooth Keyboard adopted, I chose this product. Actually, the keyboard battery is not replaceable, according to Logitech, but according to inspection with a little technical skill doable. All the more joyful was the result: the original battery out, this new back inside without any problems. The exact dimensions as the original performance and are worth gold. Now after two months in operation, I can not detect any differences in use, this battery will last between two charging cycles by as long as the original.
