Made in China. $30-$40 bucks. I had low expectations when I purchased this device. My eyes widened after trying it out. Instructions say to start on a low setting and gradually increase power, but I'm in a hurry to see results. I cranked it up to max right away. You may or may not like it. The electric pulses from the machine cause the muscles from your feet to your kneecap to tighten up. Do it while standing up. I stopped after 15 minutes and it felt like I had quite an exercise workout. Legs felt pretty good afterwards. The machine is supposed to cure swelling in the legs and feet which happens to be my problem. If I don't see any results after a week or two I will return here to post an update.As long as it keeps working its great. Takes a few hours to charge. I charge during the day so it is ready for night. Start at lowest mode and work up, if you start at the highest mode it's shocking. I previously purchased from anther vendor and it lasted a month. amazon is working much better. Price is great. I've seen others which were more expensive. If this one breaks down I will replace it, that's how much like it. I'm currently on 3rd tension. Shoxking!lThis is NOT a massager as the headline says!However, it is an EXCELLENT "Shock Nerve Simulator" and it "WORKS GREAT" for that purpose!I have "Peripheral Neuropathy" which is a very painful nerve problem on my feet!In my case, it was caused from exposure to Agent Orange while serving in Vietnam.I have discovered if you apply "Avon CBD Nourishing cream 1st", then put your feet on this mat,either when sitting or standing, it acts like a TENS Unit, which is electrotherapy treatment!Does it feel good?Not really, but the end result is OUTSTANDING, because it TAKES AWAY THE PAIN in my feet and legs!!!! On a scale of 0 to 10 and 10 being the worst possible pain, my feet pain was a 9.5 before I started this treatment! For me, one treatment of 15 minutes on setting 4 (beware the higher the number the more intense the shocks are!) I recommend starting out on a low setting and working your way up slowly.Because both of my feet are totally numb, but trust me when I say, I felt it at #4 very intense electrotherapy treatment! I actually struggled making it to the 15 minute mark, but the end result is being pain free for 6 days, then I must start the process over.IF your feet or legs are in pain, I highly recommend you buy this unit, follow my directions, as it is worth its weight in gold! :-) A VERY SATISFIED CUSTOMER OF THIS FOOT MAT!!!P.S. For me a good way to test the intensity of the pad is to turn it on and place both hands on the pad, beware you should feel a shock even on a low setting and when you do, you must decide what number would be good for your feet, once you decided, turn it off, place it under both feet (has to have both to complete the connection) set the number and wait it out till its done running or until you can't stand it anymore! :-)"GOOD LUCK and Here is wishing you a "PAIN FREE EXISTENCE" like I am having with the help of this mat!" :-)My mum has poor circulation in her feet and it works wonders. Very pleased with the orderI have very sensitive feet due to neuropathy sciatica fibromyalgia just to name a few and I was on the fence about ordering this product because of other reviewers saying it was too painful... I even have arthritis though it's not very progressed so far and as long as I leave it on power level one or two (by the way it goes all the way up to nine) there's no issue. I'm going to buy another one for work and now my girlfriend wants one after trying it... The only real downside is the device will shut off really quickly and doesn't really give you a whole lot of time to decide what settings you want to put it on but that's a very minor design issue and does not affect the product in a negative way.I love this product BUT it only lasts a few months. I have had two thinking that the first was a fluke when it suddenly stopped working. The electric impulses can be controlled for strength and changed to several styles of impulses. It's chargeable with my iPhone charger and helps to increase blood flow and energy to my feet/legs. It was perfect when I first got it but all at once just stopped working. Good product with short life.I ordered this for my hubby but I kept the item for myself, it was excellent! I notified the seller that there was only a tiny section in the instructions that made the warning about using with Pacemakers/Defibulators that people could easily miss, and he said he would correct the description... Thanks
