I'vee had mine for over a year now, and its fine...one thing though, is that it works best if you have Sky broadband as well, as it forms a Mesh network between the router,skyQ main, sky q Mini. also each box Main, and Mini, becomes a wifi hotspot, so your household wifi should be quite good after install.
i have friends who have tried to work it with a BT infinity router, and lets say its been....problematic!!
