Yup, horrible little devices that need a spacer between themselves and the backbox because they are too deep to fit, constantly run warm, and make the connection for the whole Wifi run at a maximum of half their own (rather poor) sync rate! Additionally, whatever you do, don't try and use more than one on a network at a time or you might as well go back to dial-up! (I have a sneaky suspicion you can find a review from me regards all of that somewhere).
Yes I've fitted them (not here), and then replaced them with plug-in TP-Link repeaters less than 2 months later - this was a couple of years back!
Actually setting up the ones I used was a doddle with WPS, that's about the only good thing I can say about them!
