4 in 1 - D.I.Y & Tens Unit & EMS & Massage Muscle Stimulator, Dual Channel Therapy Machine for Pain Relief, FDA Cleared Rechargeable Electronic Pulse Massager,with 12pcs Electrode Pads (RED)

This is honestly one of the best TENS Machines out there at the price point. The pads that come with it are very sticky and I tend to use it quite a bit. It's battery is easily charged using the supplied USB-C cable, and lasts a long while. It's quick and easy to use, as well as being highly configureable. The nicest part about it is that unlike cheaper TENS units I've owned and tried, this machine doesn't have the "sharp-stabby" feel which I'd put down to very good power supplying and monitoring. This also goes very high and hence can help with some of the worst pain. It can be locked too, hence making this a very pocketable unit.

I've been using a TENS, EMS, and massage combo tool daily, where it's small in size and light in weight; it's also handy for your handbag and it has quickly become a staple in my pain relief routine. The device lives up to its description—offering targeted stimulation that helps ease muscle tension and chronic aches. With adjustable intensity levels and versatile modes, it’s great for both relaxation and recovery. Simple to operate, reliable, and effective—definitely a smart buy for anyone seeking non-invasive, drug-free relief.

A brilliant and life saving piece of kit, durable, multiple different settings, holds charge well. Easy design and fits in pocket without any trouble. The only downside is the pads do not last very long and replacements can be a bit hit and miss. Great price well worth it. No medical issues like skin problems and a real source of help

This is an excellent product that comes with plenty of reusable pads in various shapes. The battery life is incredible; I haven’t had to charge it once in the month since I purchased it. It also offers versatile TENS, EMS, and Massage modes, along with a great selection of rhythmic settings.

This a great item. Works really well and charge last a good few uses. I used this after knee surgery to help with recovery and was really helpful. I have used this about 20+ times pads are still working well.

This is a great unit with very good power output and a great battery life. However, I have now had 3 of these units of which none of them work properly. All 3 units had power going to 2 pads rather than the 4 the unit supports. Really disappointed as it's a great little product. The images below show the 3 model numbers of the units. Two are the same number and one is a different model number. In all cases only 1 pad each side received power.

Returned as too painful

It does the job thx

Fonctionne étonnement bien pour cet article bon marché

This is a really good unit with loads of different settings, got it for the wife to use on her ankle and she is very positive about it's use and thinks it's doing her good, so worth every cent. East to use as well, great quality, lightening fast delivery as usual from Amazon.

I too did not quite understand how to turn the unit ON to start the message settings. I was mad and thought I had wasted my money on a cheap non functioning device. Not so! After playing around with it, it is a really great and useful device! I didn't find the Kongzee website very useful nor any youtube videos. It is important to remember the pins with the pads must be fully inserted into the lead wire which must be inserted into the device in order for it to turn on the TENS, EMS or Massage setting, and that you are using the correct A or B channel. Remember turn on (far right “clock” button, device lights up), clock button sets length of treatment, do your settings (M button changes between modes TENS/EMS/Massage), make sure both pads are on your body, a minimum 1-inch apart, pins inserted into lead wire that connects to Kongzee channel A or B and relax! I spray the pads with water and put them back on the plastic they were originally on. Supposed to replace them after 10 uses, I have not and they are still very sticky.

Works extremely well with the 4 pads. Very strong. Will recommend.
