I can’t really fault it so have given top marks.
I have tested this on my neck, shoulder, upper arm and lower back and in my opinion it works really well with the increase in power being in small increments allowing me to find just the right setting for the targeted area.
I was keen to try this out on my hands as I suffer from arthritis mainly in my thumbs so have been using it daily on my hands with the smaller pad. I have been pleased with the results and found this has gradually helped lessen the pain I suffer during the day.
The pads are reusable up to 50 cycles and you can clean them off with a small amount of water when the adhesion starts to fail. Additional/replacement pads can be purchased for around £7 each.
Overall I have found this simple to use, and the adjustment is good and has a good variety of different modes for targeted areas, and it has a useful carry case to store everything. I found it did help to relive pain and relax tightened mussels and I was also pleased that it worked with and helped relive pain in my hands.
