MASTOGO App-Controlled Wireless TENS and EMS Unit for Back Pain Relief.

I own two wired TENS units and they get heavy use due to my sciatica. They work great but dealing with running wires under clothes, accidental detachments, etc gets tiring. I'd always wanted a wireless unit but wasn't willing to pay the prices for most units. I saw this one and decided to give it a shot. Totally worth the money. Is it as powerful as my wired units? No, but it's powerful enough. I can get 3-4 hours of running time on a charge and the recharge seems fairly fast. I do have some complaints. The pads are heavy and the adhesive isn't as sticky as I'd like. And even though I followed the manufacturer's advice and dampened them slightly before use and before storing them, they still deteriorate faster than the pads I'm used to from wired units. Bottom line, plan to buy more pads (probably a little more often than other units). You ARE more limited in your coverage area since the pads have to be attached to the unit itself. That hasn't really been a problem for me given the two pad size options, but I'd love to see them offer a wire extension for locating the pads a little further from the base. My two biggest gripes are the size and the app. Since I use it mostly on my back, it means it's difficult to sit down while wearing it without turning it off since the power button is on the top of the unit. I wouldn't mind the size so much if they would just relocate the power button to the side of the unit. Oh! I almost forgot. PLEASE provide a way to turn off the flashing light when it's in use. Unless you're wearing heavy clothing, the strobing blue light is clearly visible through clothing. And lastly, the app. It's called Dr. Stim and while it's functional enough, it's pretty bare bones. It claims to repeat your last treatment but clearly falls back to defaults. I often set it to do a 60 minute treatment and only get 20. That said, I've had very few connection issues and it's easy enough to restart so it isn't that big of a problem, I just wish the app was a little more developed. I know this sounds like a critical review, but I just want to paint an accurate picture of the product. As wireless TENS units go, it is a spectacular product for the money. I've tried units that friends own that literally cost 10 times as much. I use it at least twice a week and have had it for six months now and I would absolutely recommend it to anyone looking for a more convenient, if slightly limited solution.

I’ve never had another tens unit to compare this to, but I’m pretty impressed with this unit for the price! It’s wireless, rechargeable, and has a long battery life. I control it using an app on my phone. It’s been helpful for reducing low back pain (from a herniated disc) while at work, working long hours. It’s also helped to relieve menstrual cramps. I am a little concerned about whether it mught interfere with cardiac electrical activity, as I’ve noticed some heart palpitations and heart pain/pressure a few times when I turned it up the intensity. That may just have been coincidence, but out of caution, I don’t use it near my heart or on high intensity settings. The app to use it is called Dr Stim (it was a little confusing at first to figure it out), and it connects to the device through Bluetooth. Sometimes the device disconnects from the app, just power off the device and then power on and find it using the app.

I loved the ease of setup, connection to Bluetooth and app loaded immediately without any delays. So far it’s the best TENs unit I’ve ever used even compared to prescribed or professional TENs I received from my pain management doctor and Physical therapy. I could feel pain relief immediately especially in my neck area after trying medications, massagers without any help to get pain relief. I couldn’t even go past level 2, very strong and effective. Improvement needs to be made on the adhesive for it to stick better to the skin, have better contact and last longer with use. Otherwise great product, would definitely recommend. I can’t wait to see how low it last!!!

Best tens unit purchase, worth buying!!!!

After a few months unit will not stay active.....very disappointed I really liked it when it worked. Don't want to waste money buying a new unit....buyer beware.

This product is okay. I didn’t need the fancy app connection, I prefer just slapping the stick pad to the part of my body that I need help, click the ON/OFF button, click an INTENSITY button, and click a massage variation button. Simple, rechargeable, no brainer.

Great product! Flexible easy wireless connection. Love not having tangled, restrictive wires. Comes with carrying case for all accessories for easy packing for travel. Charged once and have been using twice daily for the 2 weeks on one charge (41% left). The phone app is great but could use better instructions along with the written pamphlet. But not hard to figure out and it would not stop me from buying again

I know some people said it wasn’t sticky or strong enough but it was so sticky that I had a hard time getting it off my back the first time (which is good for longevity). I’ve kept it on all day on my back and used it at different times of the day and also kept moving it around to different points on my back and it’s still really sticky after a week. I also was worried it would not be strong enough since I always max out to the highest level on the stim machine at the chiropractor . However this was super powerful if you play around and choose the right mode. I will say so far I only used the butterfly shaped pad that comes with it but plan on using the others. I actually just ordered a second one so I can use it in multiple spots like I do with my wired tens/ems unit. I just got so frustrated with trying to use the wired one and having to avoid all the wires as I moved around so this is a great replacement. Hopefully the second unit I get is just as good as the first one I have!
