If you do or, do not, buy from MedFaxx please take the time to watch our "How To Use A Tens Video
" which will help you achieve pain relief. If tens works for you and you want long term lasting relief then be sure to watch our Infrex Video
which on interferential mode gives you carryover pain relief for hours/days or possibly weeks before another treatment is needed. The Infrex Plus has tens and interferential treatment therapies in one unit.
