With this kit I've asked 12 m² of laminate flooring in half a day, whereas before it was a hassle provided to adjust each blade. Without it there would of been impossible to perform this pose easily. The wedge wood specially adapted to blades helped me tremendously, as the metal grip. Ditto for small plastic blocks that are used to create the expansion space between your blades asked the walls tend to work and who therefore need a little space to feel good without it to wrinkle all put your soil. Cheap and super strong.
