I picked up the Dampener Attachment to use on my calves and shoulders after long days at a desk, and it does what it says. The low-impact head feels gentle on tender spots yet firm enough to work through stubborn knots, and I like that it suits both large and small muscle groups. It's not a deep percussive massage, so don't expect that kind of intensity, but for easing everyday aches it's a solid addition. Easy to swap on and off the device, and it's become part of my nightly routine.
