COMFIER Wireless Hand Massager
B07ZPV5HDF
I highly recommend this hand massager for those looking for some pain relief in their finger joints. I can't speak on arthritis, carpal tunnel, etc since I don't suffer from those diagnoses. The Comfier massages around all fingers and the palms very well with air compression like a strong blood pressure cuff. The heating is on the palms and may reach up to the middle finger joint for some with smaller hands. The device isn't too loud, build quality is excellent, and it looks very sleek. The battery life is good without the heating element on.
