Wishing to make a large batch of cakepops (again!) I was looking for something that would maybe speed up the time taken and also help with consistent shaping. Having read previous reviews I was a little unsure about this tool, as one in particular made reference to cakepops and that this was not large enough. I took a chance and am delighted with the results.
The diameter of each half ball (exactly like a melon baller) is 35mm and I personally feel that this is a perfect size to place on a 4" lollipop stick. I don't think it saved me much, if any time however, as the join in the two halves was visible and being a perfectionist I found myself removing the cake ball (easily as it is non-stick) turning and re-balling. Minor adjustments still made for a batch of very consistent cake balls and I also felt that it pressed the mixture together much more firmly than I do by hand.
My only criticism would be that when making a large batch, the scissor style handles are rather thin and so became a little uncomfortable
