I picked up the Supersoft Attachment for those days when my muscles are too tender for the standard heads. The foam is genuinely gentle, so it works well around my elbows, knees and joints without feeling harsh. It is not a deep-tissue tool, but that is exactly the point for sore, sensitive spots. The two replacement foams are a nice bonus and easy to swap on. If you want a lighter, softer touch from your device, this is a solid choice.
