It's a bit crazy how cheap this thing is considering how important it is! I couldn't live without it when making a cake. It cuts your cake layers perfectly even, quickly and easily. Such a simple product that is so essential. If you haven't bought anything besides your Wilton Student kit, I recommend this as the first thing on your list.
For those having trouble with the cake getting damaged, it's not the leveler, it's just how you're using it. It's not a serrated knife so it doesn't cut the same way.
Start by sawing slightly into the cake, then just BARELY saw back and forth with the cutting hand and slowly turn the cake through the leveler with your other hand. Cuts perfectly without damaging the cake a bit!
