Review: Belifu Dual Channel TENS EMS Unit

Yall know I like to post my Amazon reviews here. This is a review I wrote before I had this blog. Why am I posting it? Because I just loaned this thing to K and this review includes instructions to use it. So this review is for (as amazon calls it) the Belifu Dual Channel TENS EMS Unit 24 Modes Muscle Stimulator for Pain Relief Therapy, Electronic Pulse Massager Muscle Massager with 10 Pads, Dust-Proof Drawstring Storage Bag，Fastening Cable Ties. This is from February 2020 when I was still doing physical therapy. I rated this thing 3 out of 5 stars. Here you go:

I’ve been doing physical therapy for headaches and some neck damage after hitting my head in a car accident. After we get done, they always apply heat and TENS for 20 minutes. I wanted to be able to do this at home in hopes of breaking my headaches without pain killers. So ‘a TENS shopping I went.

I quickly learned there are a LOT of affordable TENS devices. At this low price point, the market is saturated. Most websites and videos that rank them are just hidden advertisements. So in my non-professional knowledge I started looking. Here’s a few things I knew I wanted that helped me with my first cut:

– Duel Channel.

– Distinguishable positive and negative terminals (NOTE: this product does not meet this requirement. Read further).

– Powerful. I like my TENS pretty strong. Just below what causes a twitch.

– Great reviews. (I trust Amazon reviews. If you find this helpful, give me a helpful vote).

– Snap connectors rather than line-in. This is 100% personal preference. Snap connectors can easily be connected and disconnected with one hand. They can be disconnected with one finger. This is super helpful, in my opinion, when it’s in a hard to reach location on my back. Also, if you were using it on an arm, I’m assuming it would be almost a must. Also, snap connectors seem to be a little more sturdy, again, in my opinion.

This got me down to two devices. I chose this one because it DOES NOT have a touch screen. Touch screens are sensitive, they break, they crack. Do you really need a touch screen? I decided I did not want that liability.

So here we are. I’ve ordered my TENS device. My thoughts:

PROS:

– The box is a perfect fit for everything. I’m just going to keep it all together in the box.

– Attached cable ties! What? That’s such a thoughtful touch. It shows they thought about how people use this. It’s so convenient. No garbage ties. This keeps all the cables so neat and tidy. Awesome. Thumbs up, for that, guys.

– Very small. I like small. However if you have crappy near vision, this might not be best for you. For me, it’s a pro.

– The included pads each have their own protective plastic sheet. I love this over having multiple pads on one sheet. It’s super space saving too.

– The included pads are in little zip bags grouped by two. I like this. To me, it shows -again- that they thought of how people will use this. You generally use the pads in pairs. These are grouped into pairs and easy to grab from the box or bag. You can also label the baggy to show which have been used. If you had multiple users, you could have the baggy labeled with their name.

– Manual has great descriptions of all 24 modes.

– Strong current. I find that around 60% is enough to cause slight muscle twitches. This means I, personally, will not ever go above that. I don’t like it that high.

– No wasted buttons.

– Duel channel.

– Can use up to 6 pads at once.

– Snap connectors (See above for why I prefer these).

CONS:

– I wish they sold a case for it. I’ll use the box, but I’m not going to just toss this all in the included bag. That’s messy.

– The product photos show color coded terminals. I assumed this would tell me the polarity of the terminals. It does not. I’ll have to borrow a voltmeter to figure this out and mark it with a sharpie.

– Only one of my wires is even color coded. On the two individual wires, both terminals are white. So not only do I not know the polarity at all, now I can’t even make sure I’m mirroring the polarity when I use the pads. SERIOUS downfall. I’m getting around this by using the double wire and will eventually use a voltmeter to mark them. If the double wire wasn’t color coded, I’d have sent this back immediately. I feel like the product photos are a lie because of this.

– No setting for constant intensity. Setting 3 : 3 does a good job of mimicking the sensation I use at physical therapy. However, it fades in and out in intensity like a wave. I would like it to be one constant intensity like I use in physical therapy. In 24 settings, not one single one uses constant intensity.

– Can only increase time in 10 minute increments.

– Can only increase timer. Cannot lower timer if you went over.

USAGE:

It’s not extremely user friendly or intuitive on how to select individual modes. I’m an engineer so it’s no trouble, but if the clock is never set correctly on your microwave, get ready. Since the manual didn’t seem well written for this, here’s how to use it:

1) Put the pads on so you can feel what you’re adjusting.

(Don’t stress about picking the mode here. Once you do it once, you’re probably just going to use that same mode every time. You got this)

2) Select MAIN MODE using side to side arrows. There are 6 types of massage aka “main modes.” Use the side to side buttons to select the type you want. I’m a fan of number three. You probably can’t feel anything because when you switch modes, it automatically turns the intensity down to nothing. So use the up and down arrows on the side of the device you are using (the side you plugged in) to feel the sensations.

3) Select Setting/Sub Mode using the ‘M’ button. Within each of the 6 main modes, there are 4 settings. The manual actually does a great job of telling you what each setting is and what it is good for. I’m a fan of 3: 3. This is “Tapping (TENS)”. The manual tells me this produces a “hard thumping sensation that massage your muscles, which can give you an invigorated and revitalized feeling.” Keep hitting the ‘M’ button until you get to the number of the sub mode you want. Again, it automatically turns the intensity down to nothing when you change modes, So use the up and down arrows on the side of the device you are using (the side you plugged in) to feel the sensations.

(Now you know what mode you like. So next time you turn it on, it will be easy. I like 3 : 3, for instance. So when I turn it on, I arrow over to the 3 Mode. Then I hit ‘M’ twice to change from sub 1, to sub 2, to sub 3. Easy peasy).

4) Adjust the intensity with the up and down arrows. If you’re using both A and B, you’ll have to do this on both sides.

5) Optional: Adjust timer. Hit the ‘T’ button to add 10 minutes to the current timer setting.

NOTE: The center round button starts and stops the pulses.

MY PERSONAL SAFETY SUGGESTIONS:

– Don’t move around a lot while the TENS device is active. Get yourself comfortable and settled before turning on the pulses. You can use the pause button (center circle) to pause sensations if you wanna move around to get more comfortable.

– Don’t plug in the wires if it’s not active. I have to have my husband place these pads on me. So I go get him to hook me up and then I go lay down, get comfortable, and ONLY THEN do I plug the wire into the device.
