Good bloody luck in using it, I got mine yesterday and they're awfully complicated for use by people who aren't well. I made a right mess of the biological bag and still have no idea how it's supposed to work. It tells you to take the tape off the sticky part whereupon static immediately stuck it to the wrong bit and you can't separate without tearing it.
Had to take 2 during lockdown - felt worse after I had done the swabbing!
