I have both the large & small and I don't have a problem with either. I use them both depending on the cake size. I find it much easier to use them when the cake is still cold. I just use a slow sawing motion & make sure that the feet are staying flat on the surface. Near the end of the cut, I remove the level. I turn the uncut portion facing me and finish the cut (hope that makes sense). This tends to prevent a tare. I wouldn't say that I love either level, but they work. I can't justify purchasing the Agbay level just yet.

Thanks so very much everyone for the wonderful information and advice. I so appreciate each and everyone of you!!!!!
