This was a valentine's day present for my girlfriend, who suffers from debilitating period cramps every month. The pain used to keep her bedridden for days but now she's able to get up and do things, I can tell it helps

This device is amazing for treating both sore/tense muscles and menstrual cramps. Aside from using it for cramps, I also use it to help with the lower back and neck pain I occasionally experience from prolonged computer use for work

endo strong!

I have endometriosis, and I never leave the house now without my Monthli device. it's become a necessity in my daily routine. TENS mode can keep me going all day and night!

My wife has tried everything for her cramps, and this is the first thing that worked for her within 15 mins of applying, good design concept

wife loves it

Customer service was extremely helpful, they answered all of my questions and helped me pick out the bundle for my wife.

My girlfriend loves using this device. she has endometriosis and says it helps calm down her flare-ups.

I almost cried when I tried it for the first time. It's a godsend for people who suffer from painful ovarian cysts

Prefer this more

After years of taking pain relievers, I developed gastritis and severe stomach irritation. I can no longer take pain relievers without getting terrible heartburns. Monthli has completely replaced my need for pain medication since I began using it. Unlike the pills,  the device only takes a few minutes to start working. this is a much healthier alternative

LOVE my monthli device

I keep raving about this device to all my friends and coworkers because it actually WORKS


makes my agonizing pcos pain so much more bearable. user-friendly design & easy to use!

The heating feature is a useful addition

I find the TENS to be very effective, and the battery can last for days if I only use the TENS. Excellent idea for period pain relief!

Love that the device is completely silent, the heating feature really helps and the fact that it's wireless is just awesome!

great natural remedy for period pain

I have been getting the progressively worse cramps every since I had a copper IUD inserted inside me about 4 years ago. Glad I found a natural pain relief solution for my natural birth control.

best tens device for cramps!

discreet under clothes, gel pads stay on all day, long battery life, heats up in seconds, no tangled cords, best purchase I've ever made in a long time!

honest feedback: it works as described

I've been using my Monthli device for over 6 months now, and here's my honest opinion of it. It works exactly as described: it heats up in seconds, the pulses vibrate to reduce overall pain perception, there are no cords, and the gel pads are extra sticky (remember to clean it with a damp paper towel to prolong the stickiness), so it stays on the body all day. I only need to charge the device once a month if I only use the TENS mode. Overall, this is a useful device to keep in my bag at all times, and I get enough use out of it to justify the purchase. In the long run, it is less expensive than over-the-counter pain medication.

better quality than others

after comparing every TENS machine that's available on the market, I decided to keep Monthli and return the others because this is the only wireless option with heating function I could find. Since I use my device all day to relieve endo pain, I need the longest battery life possible.

got this for my wife's birthday this year and she really enjoys using it, she tried it on my back for lower back pain, and it feels quite nice - warm vibration somehow stops the pain after a few minutes. Arrived on time and good customer service

My daughter has endometriosis, and I purchased this device for her to use at school, she hasn't missed as many classes lately thanks to this device helping her get through the day.

reusable and recharcheable

It's a reusable and recharcheable heat and TENS massage machine in one. I used to get those single use heat patches for when I'm at work, but those can add up quickly if you're a frequent user like me. I also disliked how much waste those single-use patches produced. Monthli device has replace all the plastic packaging and single use patches for me. 10/10

Having previously owned other tens devices, Monthli stands out to me because it is cordless and heated. Both of these features are uncommon in a traditional tens machine. It does an excellent job, and the heat function is extremely useful.

perfect, girlfriend loves it, she says she feels relieved only after a couple of minutes of using

This is a game changer!

I can't believe the difference this heated TENS device has made for my period pain. This is a complete game changer!

I'm a fan!

I used to be crippled by period pain for at least 14 weeks of the year, so this device had been a complete life saver for me. I no longer feel so helpless on those bad crampy days, and it's a very empowering feeling.

plus size friendly

I'm a plus sized user and I appreciate the cord free design because I used to have problems with cords that were too short to reach the sides of my stomach. I don't have to worry about that with Monthli :) It is comfortable to wear under pants and stays on all day.

complete lifesaver for undiagnosed endo sufferer

Thank you to whoever invented this device, the heated TENS setting is SO helpful for when I'm at work
