I was fed up of having buttercream and cake batter splattering all over my kitchen walls so thought this would be the perfect solution. Unfortunately it is not great to use. You cannot hold the side of the bowl to keep it steady while the guard is on, otherwise the batter sneaks out through the gap where your fingers are. Also, when you move the hand mixer round the bowl to incorporate all the mixture the guard starts to slip off the mixing attachments and then slides off completely. The product would be better if it had a spiral or circular slot that allowed the mixer to move round the bowl while the guard stayed in place.
