I have tried the invisigrip...I personally don't like it. I prefer to use sticky sandpaper dots.........work great and do not raise the rulers high enough to cause any miscuts......but no matter what you use, you still have to hold that ruler snuggly with good fingertip pressure and close to where you are cutting and you have to spider walk along that ruler as you cut for accuracy no matter what.......and I must say my GO cutter has definitely saved time and energy when it comes to mass-cutting........
