Yeah I was pretty pleased with the buffing wheel, it's so quick and safe. Just have to clean the lips up with rubbing alcohol to get the polishing compound off. Word of caution don't use the higher abrasives polishing compounds like black or brown, or if you do use light pressure, as it can take too much off.
Regarding the flame polishing, it's a very good solution on acrylic (plexiglass), but not so good on polycarbonate. I did a little research which was consistent with my own results when I noticed the lexan bubbling.
