yes, it worked a treat for me a few months ago. i have no idea why it works but it does.
i kept the verruca completely covered with the tape all the time. if the tape came off i just replaced it with another piece. after a week or so i'd have a pick at the verruca and the surrounding skin, which by that time had all gone soft and white, much like skin does under a waterproof plaster, and then recover the area with a fresh bit of tape. eventually the verruca had just vanished, picked off with all the dead skin i imagine.
no blood, no pain, dead cheap, dead easy, very effective, highly recommended :)
