Good product, needs better directions.

This EMS unit arrived quickly because of my Amazon Prime. I ordered this for my husband because he read about EMS units in a Men's Health Magazine and thought this would be a good supplemental way to build muscle. Do not confuse this with a TENS unit which is a different machine with a different purpose all together. As soon as we ordered it, my husband was excited to try it out and when it arrived, that's exactly what we did. The directions are a little vague but we tested it out and tried different settings. My husband said it worked well but only time will tell if it will really build the muscle in his abs.
