Product quality is great, but let me explain why it deserves only 2-star. Imagine you have remotely located router which serves as internet access point, now you connect it to network and all work great... until you switch off your PC, TV or local network would be inactive (at night, for instance). Then you will end up with HomePlug on the side of your router going to power saving mode and the only way to deactivate this mode is to reset this plug (unplugging it). There is no official way you can deactivate this mode. Some people tried deactivating it via Zyxel utility, but it doesn't save this state (it saves it in utility, but plugs would go to power saving mode anyway). Netgear Manufacturer states on their official page that it can't be deactivated and they do not plan to add this possibility in the future. It is beyond my understanding as other manufacturers have the option to deactivate this mode. 4x plugs have been returned and will go with the alternatives. Just be aware.
