I use to review items for some sellers a few years back and here is one I liked and here was my review on the item.
This electronic pulse massager unit does what it should. It helps relieve muscle soreness, stiffness, and pain else where on your body. Last night I wake up with a really bad leg cramp and all day my leg was very sore. I got this out to test it was a prefect time to get it in the mail. I opened it up and read what I didn’t do to. You will need 4 AAA batteries and there included as well. I took out the stick pads and placed them on the back on my leg where the soreness it. Then I plugged in the sticky pad to the massager at the top. There is many different levels that you can set this massager to. I started at the lowest setting because I have never tried one of these before. It did not hurt at all and upped it to next setting and i was good to so. I sat there for about 10 minutes letting this massager do its work. About 10 minutes later I took it off to see if my leg felt any better and sure enough it did. This massager really worked well and I was so happy that is did . It is very easy to work it and it is well put together . It is great quality and is about the size of a tv remote. All the settings are adjustable to set as you like it and this would be great for people who work out a lot or in pain. I recommend this massager.
