Great Replacement Brush
I’m always a bit skeptical when ordering replacement pieces that are not from the original source of a device.  But since Clarisonic is no longer in business, I had to take a chance.  That said, I just ordered one brush instead of the more economical four pack.  I am SO happy with the product; wish I had ordered four for starters.  It fits perfectly and feels great.  Will definitely order again!
