Good if you can get them to stick
These are a great size, and, I thought, great value, but they do not stick well and putting and keeping them on my upper back was very difficult. They worked well when I was able to keep them on long enough to get clothing over them to hold them in place. I've been using electrodes for many years and never had this problem, especially on first use, before. Probably easier on a more accessible part of the body.
