Defective after 9 months. The concern is not just the money lost (for 24 euros, I did not actually want to return the item, use the guarantee) but the induced problems. As windows regarded as a failure disconnect the router, I lost time with the support of the internet provider and do various tests before finding the true source of my connection breaks / disruption home network. As the switch was not permanently down, it also blurred the diagnosis for the amateur I am. I switched brands and chose a slightly more expensive model.
