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.

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.

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.

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.

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.

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

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.
