Very good tape, but not an excellent tape.  The glue is not as strong as I expected from a tape that calls itself professional duct tape.  I can still remember the old duct tape my dad used to buy.  I have no idea where he got it, but the glue on it was so sticky it would hold nearly anything, this tape isn't as good as that.  However, it tears like duct tape should, and is sufficient for about 90% of jobs you would expect duct tape to handle.  It's only the 10% I feel it is too weak for that I deduct the star.
