A great head profile - combined with non-scratch bristles
A really good brush accessory due to head shape and bristle softness. However, be warned that using this brush on machines it is not intended for will likely result in shorter lifespan due to the bristle deforming over time. I use this head with a C3 machine and noticed that, over time, the bristles started to permanently deform. This is direct result of using a accessory on a product it is not designed for, bu the I like the head profile and the bristles do not scratch delicate surfaces As a frame of reference, we are talking many months of quite active use here.
