This unit is identical to the unit my Neurosurgeon uses for my herniated L3-L4 discs. It works great,but be careful with this device. It's diminutive size belies its great power. I run mine at setting 3 and that very strong. I highly recommend this unit and the company.

I love this product,it has helped with the chronic pain in my back and legs. I can smile now.

I have Stage lV Endometriosis and had 3 surgeries in the past 12 months that left me with chronic pain in my lower back,hip and buttock. I started using the this TENS machine and found immediate relief. Now I wear it to work and find that it's very greatly helpful in reducing my pain to the point I now smile.

My doctor prescribed the Tens Unit for my Fibromyalgia. I found No gimmicks,no surprises all the information I needed to make a sound decision on my health needs. I received the Tens Unit much quicker than I thought I would. I had a great experience from the time I got to the website,shopped,ordered and received my product. I will be buying more products from Tens System in the future. I have had the Tens Unit for quite some time now and the product works GREAT! Do yourself a favor,if you need it- get it...it's so worth it!

I love this product. I have chronic pain from arthritis and this has really helped me regain the ability to deal with life. Thank you for coming into my life!

This product is great! It works to relieve pain in my lower back just as well as the machine at the chiropractor! The carrying case makes it easy to keep all together and travel with also.

Ordered yesterday - received today! The unit is great and very much the same as my physical therapist uses. Less time in PT for me! Thanks so much!

My first TENS unit I got from a doctor,and it was covered by insurance--two plusses one would think. Not so,for this unit I ordered from tenssystem.com is both better and less expensive. Just one example of "better" is that the doctor’s unit did not have a cover,so I would suddenly change settings if I inadvertently touched,say,a counter top while the machine was clipped at my waist (quite a "jolt" if the intensity button was pressed). In contrast,this unit has a cover,and,I agree with a previous reviewer,is very powerful. Regarding cost,though my previous unit from a doctor was covered by insurance,the unit manufacturer billed my insurance company monthly as though I were "renting" their product as what is called "durable medical equipment." As a result,my insurance company and my healthcare savings account together paid well over $1,000 the first three months for the machine,replacement pads,and batteries! Shocked by the Explanation of Benefits forms from my insurance,and the fact that this billing would have continued,I realized I could have purchased and had shipped 21 machines from medicalproductsonlline.org for the amount of money this one machine from a doctor cost my insurance company and me. Hard to believe,but true. In short,I highly recommend this unit I purchased from tenssystem.com. I ordered by phone from a very helpful lady,and I have had no problems with this company or this tens unit,a real bargain,in my opinion. Short of finding a way to eliminate the cause of pain,this unit is a wonderful help for living with pain.

I love this unit,my tailbone was severely damaged and thus removed,but to no avail. I am in chronic pain,more so when the weather pressure goes low and a storm is nearby. I feel the pressure even when it is in Maryland or New York. I highly recommend this unit.

This unit is all that it claims to be. Shipping was on time,great price,and easy to use. It seems to quiet my ever present muscle pain. You will not be disappointed with this unit.

I have ordered several items from this company (2 TENS UNITS)plus other selected items...I cannot say enough wonderful things about "Tens System",their customer service skills are absolutely wonderful,their delivery is prompt and their units are absolutely the best... They work great and they truly reduce the pain making day by day so much easier... Their prices are the "best I have found so far" and I will definitely order more products from them again. I highly recommend this company to anyone suffering from chronic pain,their products and services are the best,you’ll ever find!... I just wish I would have found them sooner:-)

I have suffered from chronic neck and back pain for years due to several motor vehicle accidents. This unit not only relieves my pain and spasms,but has greatly reduced the number of visits to my chiropractor and massage therapist,saving me loads of dough. The best part was I didn’t even have to pay for it,my chiro obtained it for me under my health insurance plan. All I had to do was sign that I received it. It has greatly improved my symptoms and I have also noticed I have a lot more energy since I started using it.
