Review on Magnetic Gluing Jig - Convenient 10-1/4 Inch Square Design for Effortless Bonding by Alex Tilden

Despite other reviews, I'll put the product first. Maybe it was a manufacturing issue causing problems that other people were having. But no, the other reviews were correct - none of the angles are 90%. Then, as if that wasn't enough, I must have gotten a used one (which was returned) because one of the magnetic covers was "glued" to the base (fu). It looks glued on. I tried removing it with acetone but it still wouldn't come off. Instead, I asked a neighbor to build me a box that was straight and made out of 90% wooden corners. Much better than this thing.
