I ALWAYS buy this brand as it is the best. I have tried other cheaper tapes but they don't work well at all, they don't even cut evenly at times. I will stick with Scotch Magic Tape.
I only purchase Scotch Magic Tape for the simple fact that it tears off the roll. I got so aggravated with other tapes - I have to go thru half of the roll just to get a 2 inch piece of tape. Scotch Brand tears straight every time
