More of a suggestion for the NOW TV Stick people...... The charging port on the stick is at the back and my tv is on the wall so there is no room for it to be connected. Problem with the HDMI location that won't affect everyone but would be worth considering having the charging port on the side of the stick.
If it's tight at the rear of your television for access to the USB port and HDMI port, then possibly look at a HDMI extender fly lead, where you can get different lengths and a 90 deg end connector to plug into the HDMI port on your TV.
You may also possibly see a better wifi reception signal from the stick with a HDMI fly lead extender if it's a tight space between the television rear casing and the back of the wall.
