Belifu 4 Independent Channel TENS EMS Unit, 24 Modes,30 Level Intensity Muscle Stimulator Machine, Rechargeable Electric Pulse Massager with 10 Pads&5 Set Leads Wires, for Pain Relief Therapy(Black)

Wow! Belifu really came through! They reached right out to me and offered to send me a replacement, a refund or another one of their products to make things right. I have to say that their customer service rep was so sweet and kind and wanting to fix things ASAP. I opted for a replacement unit because I really did want this to work and their TENS routines are top notch, and it works great! I love-love-LOVE the TENS and EMS routines on this unit. I also love the 4 channels being independent and so you can mix and match 4 routines across 8 electrodes and it feels a-ma-zing! I have to say that belifu really put some thought into their routines. It feels like they did some testing and figured out what actually feels good and helps with pain or muscle relaxation rather then just slapping some random patterns into their unit. I will leave my old review below, for history sake, but rest assured, if you have any problems, please reach out to Belifu to make it right, they are so nice and helpful and just seemed to want to make things right. I would recommend this brand of TENs unit 100%.*Review updated, see above!* - Well, this didn’t last past the first charge. Shame too, because I actually liked the various routines it offered compared to another brand’s unit and the fact it is truly multi-channel.Either the USB-C port, internal battery charging circuit or battery itself are defective. I tried charging it when I first got it and it didn’t appear to be doing anything, so I went ahead and tried it out with whatever battery was left and while it felt really good on some of the settings, and most importantly is truly a multi-channel TENS unit, it only lasted an hour or two before it stopped taking a charge. I busted it open and carefully removed the battery and wired it to an external power supply (don’t try this at home, I am electronics technician by education and profession) to get a little more use out of it, but it’s not really worth all the effort of all that (though it does actually power up and work that way), so in the bin it goes. All of the markings on the IC’s inside the unit have been sanded off as per typical Chinese electronics, so fixing it would be more trouble than it is worth. Buyer beware. It may work for a bit and then the battery dies and it wouldn’t take a charge.

I've got a Hidow as it was the only way to customize the treatment. One ime Being the Only device with independent channels.Not anymore!!!!This is moderately priced and worth every penny. Each channel can have a different mode of operation & intensity providing a customized treatment. This also has easy to switch between EMS and Tens functionality. The EMS functions include mimicing exercises . That is extremely valuable if I've missed the gym or am wanting the benefit of a second workout without going to the gym.There are placement guides for specific ailments and the instructions explained it all very clearly.A belt clip lets me wear it as I do things like dishes or cook. And shuts off automatically after the timer goes off so you don't accidentally drain the battery. The buttons are clear and easy to understand.I'm extremely happy I got this.

I like the price. I bought it solely for the TENS unit functions. The fact that it will provide more channels than I could possibly need is a bonus. There are four channels, which translates into being able to attach four wires, each with two electrodes. It does both TENS and EMS, but I only use the TENS functions. It has lots of pre-programmed settings for each mode. The electrode adhere to the skin well and have plenty of power. The rechargeable battery (via USB-C cable) lasts a long time.It is not without problems.The instruction pamphlet is printed in extremely small font. Almost impossible to read! It is also lacking in information. For example, there is an extra wire lead that will take four electrode pads, but there is no mention of it in the instruction pamphlet. Typically the wire leads on TENS machines only use two electrodes.The pre-programmed settings work, but they are confusing and there is no technical explanations of them. They simply have small icons that look like acupuncture needles, hands doing various massage techniques. What do they all mean? It's just not explained. The user is left to sample each one and find the settings that work. Don't get me wrong. You can find settings that work for you.Once you have identified the settings and electrode placement that work for you, it would be great if the unit would remember those settings for future use.
