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.

Easy to use and very effective. No more wires! The sticky pads adjust and adhere well, plus, the units keep a charge. Very happy with this product and highly recommend

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.

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.

Great product! Love the fact that it does EMS & TENS both. The app is pleasant to use as well. Comes fully charged which is amazing! This product is very portable which is nice for someone who needs to do daily activities but needs to use something like this.

I tore everything there is to tear from elbow to shoulder when my horse decided to rodeo. I had to wait three months for surgery because my doc's assistant gave me steroids before ordering an MRI. It is excruciating. It is so painful that my normal low blood pressure is near stroke level. I have bought every heating pad, cold pack, wrap and whatever I could find to help me get through this. I finally ordered these. Don't know how it works, but sometimes it's the only thing keeping me sane and allowing me to sleep. Don't know if it actually makes it less painful or it's that it distracts me from the pain. I don't really care. It is helping me tolerate an intolerable situation.

This is device is alright, but not what I was hoping for. The Bluetooth connection of the pods is easy and stays connected, the battery life is very good, and the stickiness of the pads is still strong after multiple uses. My biggest complaint is with the mode options. First, there are many different modes, but the pictures of body parts are unhelpful in figuring out the rhythm each one provides. Additionally, there is no option for constant stimulation without a rhythm, which is what I prefer and expected. You also cannot adjust the frequency of the stimulation. If I didn't want a high-frequency, constant stimulation, I might be happy with this device. As it is right now, though, I would not purchase again.
