i've had several of these, back when they were brown & now that they're silver with an ionic button. The VS540 replacement attachments fit perfectly. I keep 2 sets of replacement attachments at all times.http://www.amazon.com/Vidal-Sassoon-Brush-Attachments-Coms/dp/B004BBNYNY/ref=sr_1_1?ie=UTF8&qid;=1325745739&sr;=8-1
