REVIEW – Many of us suffer from sore muscles or tension.  Do you know what helps?  A good neck massage.  But having a cooperative partner that is willing to give you that massage is a rarity.  Hiring a masseuse can be expensive.  RelaxUltima could be the answer with their neck massager. So yes, I am willing to get some regular neck massages to keep you, our faithful readers informed.  I’m a team player.

What is it?

The RelaxUltima neck massager is a TENS-based massager designed specifically to work on the muscles in your neck. TENS (transcutaneous electrical nerve stimulation) is a method of pain relief involving the use of a mild electrical current. Typically small, battery-operated devices, TENS units use electrodes to introduce electrical pulses that can release endorphins and other substances to stop pain signals in the brain.

Design and features

The massager is a U-shaped device that is designed to fit around the back of your neck. The pads along the inside rest on the sides of your neck, cushioning it as well as keeping it in place.

In the photo above, you can see the charge port on the left end.  To open it, you dig a fingernail into the slot in the cover and pry it out.  Behind the cover, we see the micro-USB port.  Can anyone say “USB-C”?

The shiny disks on the back are the electrodes.

These rest on the back of your neck. They introduce the mild electric current that does the actual work.

Speaking of electricity, let’s talk about the cautions. From their website:

People with the following medical conditions should NOT use this product:

  • pacemaker or any other implanted medical device
  • artificial heart, lungs, or any other life-saving electric devices
  • metal implants

Do NOT use this product near the following:

  • electronic medical devices
  • gas, explosives, and other highly flammable material
  • near or around the heart

The unit turns off after 15-minutes of use, and they recommend no more than two 15-minute sessions daily.  I find this interesting, as a little Google research produced a huge number of TENS websites that say that you typically need 30-minute sessions for best results.  Not sure what to make of that. Back to the design…

There is an oval shiny silver button near the charging port.  That is both the power button and the power/charge indicator.  When on, the button glows blue.  When charging, it flashes red and then glows red steadily once fully charged.

The small remote has four buttons.

They are as follows: heat on/off, massage mode selector, intensity+, intensity-.


The unit ships partially charged.  Before use, plug it in until the red light stops flashing.


All the descriptions are fine, but the proof is in the massaging.  Let’s get into it!

The massager is comfortable to wear.  It rests easily on the neck and stays in place well.  The instructions say to remove any metal jewelry from your neck and then slightly dampen your neck with a damp towel to improve the conductivity of the electrodes.

Once the massager is in place, you hold the power button for three seconds.  The massager beeps to indicate power is on and the button glows blue.  For me, the massager didn’t do anything when turned on.  Pressing the + button to increase the intensity got things happening.

To be clear, this is not a traditional massager where pressure is applied to muscles.  The TENS system applies a mild electric current that helps your body produce endorphins that help to block pain.  If you’ve never used a TENS system, the sensation is a little weird.  While there is no physical pressure being applied, there is a distinct massage-like feeling.  It’s more of a tapping and vibrating feeling than a rubbing and pressing feeling.  Still, it feels pretty good.

The heat button on the remote turns on the 107-degree F heat.  I thought that 107 was perhaps a little bit of overkill, but was pleasantly surprised.  It seemed just right – not overly hot.  The heat is nearly instantaneous when you press the button.

The three massage modes aren’t described in the documentation. My best interpretation of the modes are:

  1. Mostly tapping with some vibration
  2. Balanced tapping and vibration
  3. Mostly vibration with some tapping

I prefer more vibration than tapping, so that mode was my favorite.

There are 15 intensity levels available.  I didn’t like anything above level five or six as it gets quite intense.  At level three or four, I sat and watched TV for 15 minutes until the self-timer shute the massager off with a beep. In the end, my neck felt pretty good.

My wife tried it out and said that it felt “OK”. Our daughter was visiting so she tried it out as well.  Her reaction was interesting.  She said it felt unlike anything else she had felt, and that she wasn’t sure how she felt about it.  But the longer she used the massager, the more she liked it.  In the end, she was a fan.

When my daughter was using it, I closely watched the back of her neck. For the most part, I couldn’t detect any movement even though she felt a distinct massage motion. It’s really pretty interesting experiencing the TENS massage. In fact, putting my finger on my neck between the pads, I felt nothing, even though my neck was getting vigorously vibrated.

What I like

  • Comfortable
  • Silent
  • Heat felt great
  • With 15 intensity levels and three modes, just about anyone should find something they like

What I’d change

  • Standardize on UBS-C charging
  • Include some documentation on the different massage modes
  • The charging port is a little difficult to open
  • Clarify the usage limits as they seem to disagree with the general consensus on TENS usage

Final thoughts

I wasn’t sure what to expect from the RelaxUltima as I had never experienced a TENS unit before. Sometimes, when I’m writing reviews, my neck does get a little still from looking down at my laptop.  As I’m writing these final thoughts, my neck is getting heated, tapped, and vibrated by the RelaxUltima, and it feels pretty good.

Of course, if you have any of the conditions listed in their list of caution conditions, you should look elsewhere for a solution.  With the combination of the physical vibration sensation, heat, and endorphin-releasing TENS process, RelaxUltima offers a nice solution for neck pain and stiffness.

  2. I have two titanium hip implants so I guess this unit is off limits for me? They are a long way from my neck though…and pretty solidly in place.

    1. Anthony:
      I should have mentioned that I have a titanium right hip and had no issues using it. Your mileage may vary.

  3. Garry: Thanks for the reply. Could be the mention of the caution on implants is done for liability reasons.

    Garry, the picture in the performance section worries me. Please don’t touch anti-Garry or you’ll annihilate each other.

  5. I have titanium steel in my neck. I’m disappointed that I can’t use this massager. My hubby gave it to me for my birthday. I was so excited and used it a couple of times, and then was disappointed when I read the metal restriction. Is there a way I can find out that it’s okay or not okay just by the results or bad effects from using it? Is it a caution or a warning? How serious is it?
