Mine’s been sitting on a side table since I got it and it hasn’t moved. The wall bracket is still in the box somewhere. As long as the surface is flat and the cord isn’t a trip hazard, using it freestanding seems like the normal way most people run these.
Wall mounting changes things a bit since the remote has to reach up at an angle, but mine still clicks over from the other side of the room without much fuss. I do notice I have to lift my arm a little rather than just poke it from under the covers. Small price to pay for not freezing on the way to the dial.
