Most massagers of this type do one job on one body part. This one is built around a removable middle partition: leave the sponge in and the two channels take a foot each, or pull it out and the open surface becomes a single pad that can be laid against the low back instead. That one change turns a foot unit into something that also works on calves, thighs, arms, and the waist, which is a lot of coverage from a 16 by 10.5 by 9 inch box. Inside are two different kinds of node working together. Kneading nodes press and rotate in the way a thumb would, while vibration nodes run underneath at a finer frequency, and constant heat runs through both to warm the feet and encourage blood flow rather than just adding surface warmth. A wired controller sits on the end of a cable so modes and intensities can be changed by hand without leaning over, and a default 15 minute timer stops the session on its own. The cover is waterproof faux leather, which matters more than it sounds: it is wear-resistant, does not absorb sweat or lotion, and wipes clean with a cloth rather than needing a wash cycle. The whole unit weighs 2.5 kilograms, draws 24 W at 12 V, and takes a foot up to US size 8.5. It suits relaxation at home or in the office, and arrives in Grey.
