Marta compares the "Rolls Royce of brushes", the Clarisonic Skin Cleansing System, to the contender, the Sirius Skinsonic Skincare System. Though Marta likes the Clarisonic because of its larger brush head and superior oscillating action, she found that the battery operated Skinsonic, which comes with four different head attachments, left her skin satisfyingly smooth. At a quarter of the cost of the Clarisonic ($225), the Skinsonic is a deal Marta can get behind. See Marta's full analysis here.
