Takes some warmup time but overall great unit
This unit is a decent TENS unit. It's not super powerful but it gets the job done, which is good so you don't accidentally over do it. The heat on the unit takes a little time to warm up but it gets there.<br /><br />My wife has terrible knots in her neck and shoulders all the time and this helped provide a great amount of relief to her neck. You will need to clean your neck with a damp rag to get it to work effectively but that's a minor inconvenience.
