Med-Fit 906A Premier 4 Channel Rechargeable - TENS EMS Combo Muscle Stimulator for Pain Relief and Muscle Strengthening

This is very similar to a model I got long ago called the DuoStim, which was removed from over the counter sales, probably due to the power levels. I am pleased to say that even though this model has lower voltage (50 as opposed to 80), it is still quite powerful, and retains a feature I found in one of the earlier units I had - the ability to use different circuits in close proximity without degrading the power applied. This model is also quite a bit less expensive. There is also a very similar model from iStim, but that is priced a bit higher than this. I have one of those and consider them pretty much identical, and equally as good. It is even mentioned in the instructions that one may use electrode sets in very close proximity or even crossing paths without problem. Just be aware that the channels will add together delivering more power to the treated area. I was worried about the life of the charge in the battery, but it lasts far longer under heavy use than I would have thought. I have had it last over a week of every day use (for an hour or more a day) before the battery needed recharging. I am very pleased with that. While it is outstanding for TENS use, it is also very capable for "off the book" estim uses, provided one exercises proper caution - again it is very powerful. It also adds some pre-programmed settings, such as a rise from 2-125hz, that I personally have found useful in this kind of application. You will have fun exploring the presets. I do not know how it will hold up over time, but the older model from a different vendor has lasted nearly a decade. I consider it the best TENS unit I have used so far, especially for those "other" uses. Highly recommended.

Once you get the pads in the right place, it's very effective. I've had an issue with the left side of my neck for at least thirty years from playing guitar and jumping around and hauling gear. The weight of the instrument combined with playing practically every day since 1977... My lower left neck is like a rock. I just used two pads in the recommended position for that area and experimented with the settings and after a couple hours, The rock had become soft so to speak, and I could actually push into the muscle which for so long was just so bound up in that spot just above where the guitar strap sits on your shoulder. Needless to say it was very tender and a bit sore after, but I noticed a significant improvement almost immediately. Another thing is this is not a toy. You can hurt yourself with this thing. I personally haven't yet, but the potential is there to give quite an uncomfortable shock I'm sure. So many units to choose from and the option anxiety started kicking in, I almost didn't order one. Plus you can spend hours shopping for one item because there's so much to look at, a half an hour at a time is all I can stand. I think this unit is a solid deal for the money so far. The basic presets and full control over power, pulse, frequency and even width which really gives you some juice.

I have trigeminal neuralgia and this has helped so much with facial tightening in between dry needling. It is easy to use with its booklet of instructions and illustrations on lead placement on the body. Besides facial treatment, I have used it on my neck and shoulders to help relax my muscles and it doesn't disappoint! I have used this for years and have only need to charge it once or twice. Replacement leads are easy to obtain online when these wear out, but you are given a nice supply of them with this set. I would recommend, and have, to anyone in need of help with their muscle tightness.

For anyone who wants the EMS part of it and 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. 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. The difference between this one and the smaller one that has the EMS is the way you adjust the buzz. 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. This one that's bigger, you don't need reading glasses to see the large fonts. Wish it was 1 inch less on top and side to fit into pocket better and be less heavy. The screen does not need to be that big. It does turn off by itself when it reaches the time you set it on. I would say the over all feel of buzz is more even than the smaller one. This 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 at top and C at bottom. 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. 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.

Me canta siempre tienen cosas de calidad. Solo no me gusto el cable Del cargador lo tine muy corto

لايستحق كل هذا المبلغ به اعطال بمدخل محول الكهرباء

配送についての連絡はキチンとしてくれたのですが。 日本語の説明書が無く使い方がわか、なかったのが残念でした。

This brand gets better than the first brand I bought...even cheaper. I loved this and would recommend it to my patients needing TENS or EMS machine at home.

الجهاز بشكل عام جيد ولكن البطاريات الصغيره المصاحبة للجهاز لا تقبل الشحن فقد اوصلتها بالكهرباء قرابت الخمس ساعات وكانت النتيجه غير جيده للاسف فمجرد فصل الجهاز عن مصدر التيار المستمر توقف الجهاز عن العمل وفي هذه الحاله يجب توصيل الجهاز بمصدر الكهرباء بشكل مستمر
