INSMART 3-in-1 TENS Unit Rechargeable Muscle Stimulator EMS Dual Channel with 10 Reusable Electrode Pads 36 Modes for Back Neck Pain Muscle Therapy Pain Management Pulse Massager (Black)

Key item features

  • 3-in-1 Pain Relief TENS Machine. The 3-in-1 TENS, EMS, MASSAGE machine is an excellent choice for shoulder pain, lumbar pain, and back pain relief. This muscle stimulator activates a specific natural pain gate mechanism and relaxes your body. TENS offers pain relief in a non-invasive and drug-free way. EMS improves muscle performance. MASSAGE helps relax your body and dispel fatigue.
  • A/B Dual Channels. 36 Modes and 20 intensities are included in a little TENS Unit with an A/B channel which can offer the relief option of 2 or 4 pads at the same time. This portable stim machine can be used in home, office, or traveling. The treatment of this home TENS Unit is the same as physical therapy offices' muscle stimulator.
  • More effective pain relief than other TENS/EMS units. The independent channels A/B can work in different modes and at different intensity levels (e.g. in channel A you can select mode 7 with intensity 3 for the shoulders, while in channel B you can select mode 25 with intensity 5 for the back).
  • Powerful battery:
  • The package includes a USB cable that connects to a wall charger, mobile power supply or laptop USB port for charging. With up to 20 hours of use on a single charge, it is more environmentally friendly than AA batteries and lasts longer than other machines. Our Tens units come with a power indicator to remind you to recharge!

Great TENS Unit!!!

This is a very good TENS unit. In my past I've paid as much as $250 for TENS units. And then I get this one for about $40 and it had more settings and works better than any $250 one.

This works as well as an ice pack but results last longer, the unit is small enough to tuck in a pocket and walk around, put in a travel bag. It has 2 ports so can use on 2 separate areas of body i.e. neck and lower back. Each port has 2 patches, various sizes in box, that can be adjusted for different intensity. There are 32 different pulse styles. Very worthwhile investment.
