The key works well enough and at a distance of 5 meters (certainly limited by the connected devices). However, it comes apart too easily because the hull is just clipped and it did not take long for the fasteners yield. A drop of glue was enough to fix the problem. For the past 6 months, I let continually plugged into my laptop, its rounded shape and its small size does not harm the environment (table edge, hits against accidental pressing or other object). I do have some minor stalls nentraînant not provided disconnection. The disadvantage is that in case of failure, you can not know which side it comes from, bluetooth or key device. I have not installed against by the driver provided but let Windows run and everything is going smoothly.
