Wireless Tens Unit Muscle Stimulator - Two Sets of Tens Unit Massager for Pain Relief - Up to 12 Mode 20 Intensity Portable with App Controlled Bluetooth TENS EMS Muscle Stimulator Machine

I had NO idea they had wireless tens units! I ordered it last night and I woke up this morning and it was on my front step! I couldn't wait to try it ... and it did NOT disappoint. It's easy peezy to setup using the app on your phone. Charges fast and it WORKED! Keeping my fingers crossed that this is what I needed to get relief from my back pain caused by sitting at a desk all day. I won't lie, my favorite part is that I don't have to fuss with wires any more.

This is a top-quality product that provides great lower back pain relief. I've received past professional physical therapy for my back pain, which included electrical stimulation at the end of each session. The MASTOGO device feels very similar and seems to perform with equivalent benefit. My first use was with the double pad stimulator applied to my lower back. I chose the "back" setting at middle intensity for 20 minutes. I found relief the same hour! I look forward to trying the several other stimulation modes to experience how they can provide future benefit as well. In addition to its beneficial performance, I really like that it wirelessly connects to my iPhone through the MASTOGO application, which is intuitive and easy to use.

Bought it for back pain an the results are great!, the amount of pain killers has decreased to almost zero. Easy to set up and very comfortable wirefree tens let you use it anywhere anytime. Battery life is pretty good!, you can use it many times before needing to charge it.

Absolutely love the wireless option. The larger pads make it much more effective. Also love the option of tens and ems. Great device well worth the cost.

If you’re in the market for a TENS unit this is for you! Works as advertised and delivers great therapeutic relief. Cheap makes it a great first timer’s choice.

Yesterday at our physical therapy office I paid $50 for a great tens treatment for my lower back pain. So I ordered this MASTOGO unit thinking it would at least be a cheap imitation, but WOW it kicks! I just finished a 20-minute session and I can feel the relief. The pain is gone. It works 4 seconds on, 2 seconds off with power adjustable from 1 to 60. My level is 10 so I have lots of headroom for future treatments, which I'm eager to do again. Buy this unit. You'll need a smart phone to download the app from Google or Apple. It has already paid for itself.

After seeing family members with the wired versions, and how limiting they seemed to be, I bought this. It was easy to set up (install the app, turn on Bluetooth, detect the device(s), and enjoy). I've used it at home and work without issue. Great purchase.

I originally purchased this as a gift for my husband to help with his shoulder pain. I also had a total knee replacement four months ago and have been dealing with some new discomfort myself, so I decided to try it as well. This product actually exceeded my expectations. Overall, it works very well. The pads are extremely sticky and generally adhere well, although I’ve noticed that the edges—especially toward the outer areas—don’t always stick perfectly. Occasionally, the pads disconnect from the app or display an error saying they’ve lost contact with my skin. That said, the product does what it’s designed to do. It has helped reduce both my knee pain and my husband’s shoulder pain. For the price, it’s a solid value—especially compared to similar products that cost $200 or more.
