The product, according to the description, is perfect. But once installed, it is quite another thing. We need your electrical installation NICKEL, you must also disconnect all your phone chargers, devices that could possibly blurred the PLC signal etc ... Neli The service is not very present in their service. Looks like everything is sloppy! Really disappointing especially when you see the price. The concept is great but there is still much work to be done before the product is excellent !!! Pending V2 ... I give it 1 star and maybe even too much.
