I was disappointed with the cupcake plunger, as unlike the batter dispenser from the same company (seperate review) it doesn't please quite as much. I used it on my standard cupcakes (bigger than fairy cakes but smaller than muffins) and I think it's too big and takes away too much of the cake! (Ok if you want filling as opposed to sponge!?) It did however work well with larger muffins - Maybe as an american design, they have bigger cupcakes in the U.S!? It is a shame as it is so popular to have cupcakes with fillings now and we really need a decent product to create a perfect hole, sadly though, for me, this isn't it.
