Lo usa mi mami y le funciona muy bien

Hasta ahora me ha funcionado bien , solo que la batería se acabó muy rápido, he comprado baterías recargables, creo que debería traer una batería recargable; en lo demás cumple con lo especificado

Not leaving a huge lengthy review. It works amazing my back pain goes away and it's very easy to use, best purchase ever!!!

This TENS NMES unit is programmable, allowing me to set parameters to decrease pain, facilitate healing, or activate muscle power. I’m a licensed rehab therapist, and use these in private practice. I also teach patients and sports clients how to use them on their own. The company is very reliable. Do business with confidence. You can’t beat the features at this price point, it’s a real bargain.

Love this unit! It is easy to use, the pads stick well to wherever you need pain relief and therapy. The number and variety of programs will meet your needs! I highly recommend this unit!! It is so soothing, I actually fell asleep using the unit on my back and neck.

About 8 years ago, I was prescribed an EMSI TENS unit. I was sent a second, upgraded unit about 5 years ago. I received EMSI electrodes monthly, so I wound up with a stockpile (6 dozen) of electrodes. About 4 months ago, both units stopped working.With the nerve damage and pain after a foot surgery, I wanted to keep using a TENS unit to slow down the nerve damage, so I tried to buy a new EMSI unit and apparently that requires a doctor's prescription since the EMSI site doesn't have a shopping option.I found a used EMSI unit on eBay for $45, but I wasn't excited about that option. I started trying to find a unit on Amazon that I thought I could use with all those electrode patches and I FOUND IT with this unit. For the cost, I was getting a new unit that could be returned if it wasn't compatible with the electrodes.I've used it every day (3x daily) since it arrived. See the EMSI patches on my surgery site in use. This unit came with 1 pack of electrodes. You can see they are a bit larger than the EMSI patches. The unit has a very good, clear instruction booklet with it. And the unit is easy to use. I like the fact the controls are protected with covers. That prevents accidentally hitting the controls and getting a painful shock.All in all, I would buy this unit, particularly if you have EMSI electrodes you'd like to use. As I'm writing this review, the electrodes are attached to my calf hopefully stimulating blood flow to the nerve-damaged foot.

Pocket size and clip to be easy to carry. EMS part, not the Tens Unit, this is a good one. Very few have the EMS you can control the number or Hz on sold on here.Any device that doesn't show Hz in the picture means you're not able to adjust it which defeats the purpose. There are some that show EMS. If you don't see EMS and Hz on screen, it's not for you to set vs. they preset it. That won't have the same effects.Instruction manual for all tens unit are not useful. It doesn't tell you the details. Those wanting the EMS, lot of times it's the professionals that know how to set it. No manual tells you what does what.Anyone not familiar with Tens Unit, it is not consistent sensations. Not designed to be. It's meant to have your nerves react so no matter what you set it on, you're going to have surprises vs. anything more consistent with a pattern. Not intended to use while operating any machinery. The way the pulses work will be a surprise. Many Tens Unit sold on here and they all do the same thing.The EMS part is what helps you on the pain relief. Your body produces natural pain killers called Endorphins and Enkephalins. Nice to know eh?If you want pain relief without the medicine, this is it. You have to use it on a daily basis for the body to keep up. No, you can't set it at the highest number and think you're going to get a full on relief and speed up the process. You end up feeling more pain afterwards. So if you do feel pain after, it's normal. The body isn't used to it at that setting yet.Best way to use this is to set it at 100 width, 85 Hz. Then after a few days, got up an increment on the width. Keep going on it till you reach 300 since that's max on most of these devices. Then increase the Hz little by little till you reach 150 which is max.By setting it at 100 width and 85 Hz, you get the consistent buzz. If you set it at what ever number, it will not be consistent and it will pause in between. Set the ramp at 5.Many folks fuss that it doesn't work on this and other devices. It's due to not having someone that usually deals with this to instruct how it should be used. It's something you gradually build up on. Once you build it up to max, then it works the way it should and even before then.Don't use it more than once during the hour. Always give it 1 hr time gap or more. Set it at 15 min for a while and then move up. I understand one can be in a lot of pain. You end up in more pain if you try to set it at max. As for how high of a buzz you want to feel to start, I would say stay between 5 - 10. You can go higher, but don't suggest it if you're new.This isn't designed to be same as meds to work right away. You have to build up to it.Endorphins is hat last about a few hours when it's set at a certain level. Enkephalins last 24 hrs. When you have it set to full potential, it works very well. You have to build up to it. May take a few weeks.Never stick the patches on your neck, head or over your heart.Smaller one is nice since it fits into pocket. But the turning knob to adjust buzz is very lacking so you can move it up a tad too much and feel too much. It's as if they designed it with kid fingers. It should be designed with buttons, not a knob to turn. Moving up 1 number can be a stronger buzz than you want and need.The larger version of this that has the buttons has a more consistent build up on the buzz which is nicer. But it is a lot bigger is what makes it not as convenient to carry around and it does not come with clip that this small one has.The big one does turn off by itself when it reaches the time you set it on. The small one beeps for you to turn it off. Bigger one has 4 outlets which mean you can have 8 patches. The smaller has 2 outlets.For all those who wonder why sticking 1 patch doesn't work, it's because you need the 2 patches on your skin to work. Whether you want to stick the 2nd one next to the 1st one or across, the idea is to use 2 patches.The patches do last a while. You rub a light, damp towel over it after use to keep it clean and sticky.Both designs look as if it was created in the 1970's and nobody cared to update it. Bulky and no designing it to be easier to use.Set it on EMS if you want a consistent buzz. You can change things around, but I'm not messing up the setting that works best. This is good for anyone with chronic pain. If you have some temp. pain due to surgery and the idea is to be on this vs. meds, it works if you give it time.Hope this is more helpful than the manual.From there, I would sugg. you use it once a day or skip a day to get your body used to it so that when you're in a lot of pain, you're not starting all over again.
