Small device delivers big!
This little device has been a life saver! After hearing about it from a co-worker, I decided to give it a try and WOW! It really helps and I just put the device into my pocket. I can wear it to work and use it all day. I just tuck the cords into my pocket with the device. I use it for my lower back pain and for my hip tightness. It helps alot!!!

Worth getting for aches
Read directions, place it where needed on the body and press the go button. Relief is significant though not a total healer to make a complete healing. It’s like taking aspirin and it has a period of time to be an effective pain reliever and then you take aspirin again. I do like it and it works well. Actually bought a second one for the wife.

Good little device
Purchased one of these over 10 years ago, stopped working this year. Purchased the new device and used the cord to test the other one only to find out it was the cord that failed and not the device itself. Love this little gadget for those annoying muscles that cause pain once in a while.

Best tens unit I have purchased!
It works as well as the one my PT uses. This is a simple to use, incredibly effective unit. I highly recommend it. The pads are wonderfully easy to reuse. The settings are very easy to understand and offer a variety of modes/patterns and intensities. A great value for the price.

hard to use
This product was a little confusing compared to other similar products, it took me a while to go through all the modes and determine the differences and honestly i did not like any of the modes very much. the intensity was hard to control and jumped from very low to very high pretty quickly. I found that the 3rd setting was too low intensity to do anything but the 4th shocked me and made my muscles twitch. i bought this device to hold me till my new livia comes in and i have to say the livia is a whole lot better

Bad product
Bought Omron Tens massager thinking it as a good brand. but found it not working as per the specifications discribed, no pulse noted even when run at Max level , asked for return, Amazon executives asked for 72 hours for update. no calls or update received even when more then 72 hours are over. very bad product. Nobody should buy.

Pain relief
It helps a lot. I bought this for my lower back pain. This has 5 modes and 10 speeds. I usually use it on mode 4 with speed 1. I am really satisfied with the product.
