Review on Gaffer Tape Roll - Extra Large Size! 3 Inch X 40 Yards (120 Feet) Black Tape For A Wide Range Of Applications - Durable And Versatile Tape For Gaffing, Ducting, Binding, Flooring And More by Joel Wright

Despite the advertising and marketing, my simple "tape a box closed” test shows how awful this tape works.This box has been taped close for about 1 week, and sitting on a breakfast table in 72 degrees of conditioned air.And outside of the flaps of the box, there are no stresses pushing from within trying to burst out.Still, the tape cannot maintain its adhesion.Absolutely the worst tape I have ever used.A complete waste of money.Update - 2 Months Later.The tape is so bad and unreliable that I ended up just using it as very expensive "masking tape."But here's the kicker, because it doesn't hold very well, if I want to leave it masking my projects for more than 10-15 minutes, I actually have to use 3M masking tape over this gaffers tape to keep the gaffer tape down.
