My slotted ruler didn't last long. It cracked at the weak slot points.
In my opinion, if you're not careful about where you put any ruler, you won't get straight cuts, slotted ruler or not. The key is to make your cuts perpendicular, meaning the ruler is perfectly square with the fold of the fabric. If it's not, you will get a V in your cut.
