I’m very satisfied with both the product and the service — highly recommended!

Absolutely life changing device. I have seen such a difference in my symptoms since using this. Less pain, fewer mental health concerns. Customer service has been impeccable.

Amazing customer service and support. Nettle has helped with my PMDD symptoms and would highly recommend it to others.

I have now been using Nettle for over a year and it is life changing.
PMDD symptoms are vastly reduced.
It is very easy to use, I have very thick hair and it hasn’t been an issue.
Customer service are very responsive and were very helpful when I had charging issues.

I’m one of the early buyers of the Nettle neurostimulation headband in France, and I’ve been using it since the very beginning. I can honestly say it has completely changed the way I experience my period.

I used to have extremely painful periods — the kind that forced me to take painkillers every single month since my very first cycle. I’m 30 now, and since I started using Nettle, I haven’t taken a single painkiller. For me, that alone is absolutely huge. Some months my pain goes down to almost zero, and even on the more difficult ones, it’s still nothing compared to what I used to go through.

For mood regulation, I didn’t notice a major improvement. However, knowing that my pain will be low or manageable has removed a lot of the fear and anxiety I used to feel before my cycle. That in itself has made the whole experience emotionally easier.

I also noticed that my period flow has become much lighter — I can’t say for sure if this is related to Nettle, but it has been consistent since I started using it.

I have experienced ongoing technical issues with the device and had to send it back multiple times. But the Samphire team has always been incredibly responsive and helpful. They answered quickly, guided me through the process, and always found a solution. Their customer service really stands out.

Even with the technical problems, I genuinely believe this headband has drastically changed my life, and I truly wish it could be known and accessible to every woman who struggles with period pain.

Most incredible decision I have made to support my health. My pain is much more manageable, my quality of life has improved drastically. Also, the customer support is out of this world. I recommend this to everyone I believe it could be useful for. Incredible 100/10!

Using a Nettle has changed my life. The week before my period, are now doable.

Before Nettle, I felt overwhelmed, anxious and even angry the week before my period. Now that's replaced with a bit of tiredness and most importantly my happiness stays throughout my cycle.

This headband is an absolute game changer!! I am literally recommending it to any woman, who deals with an overwhelming luteal phase.

Thank you so much Samphire Neuroscience, everyone I have been in contact with has been so helpful and kind.

This is truly one of the most honest and amazing companies out there. Their customer service goes above and beyond every time. You can really feel that they operate with integrity and strong ethics. Also — the headband works amazing!

I subscribed to the Samphire app to see phase-based suggestions I can act on. However, I didn’t find a strong “wow” factor to continue the subscription because most period-tracking apps already offer similar features like predicting periods, tracking symptoms across phases, and explaining what’s happening in the body during each phase.

But my question is: What am I supposed to actually do with these tracked experiences? I already know that I’ll go through certain physical and emotional patterns in each phase. If there are no actionable insights, habits, or real behavior guidance based on the data, then simply tracking what I already know doesn’t feel meaningful or useful.

The app also has sleep and step goal tracking for each phase, which is a nice idea, but I’m confused about how it’s calculating these metrics. There was no prompt to connect a smartwatch or any external device, and I’m not able to see the tracked metrics in the app. I feel like the data isn’t actually being collected, or I’m missing something. If the app relies on a wearable device, it should clearly ask for it. Right now, I’m left unsure about how these goals are being measured.

After about 1/2 year, my Nettle is still working and I keep feeling better! Especially my mood in the second half of my cycle - it is not only „less instable“, but genuinely happy! Also, the App is improving continuously.
The only problem is the price of the delivery to germany (of the refills). 18 Euros. That’s too much, but I guess we have to thank Brexit for that, not Samphire Neuroscience. They reacted immediately and now allow for 3 refill packages to be purchased at the same time! Love the service!
It’s the product that counts and it does make a huge difference in my life!
Thank you!

I have had a wonderful three months so far. The Nettle headband has helped with my cramps and my PMDD extreme emotions. The app that you use along with it has meditation for each phase of your period. It also let's you log all of your emotions, over or under eating, really anything that you associate with your menstrual cycle. The longer you use it and the more often you log things the more info it has to show you how you are really feeling and doing. You can compare the changes over the months easily. The people that work at the company and I think the founder are so responsive and helpful with every question and issue that I have had. I really love this company. It is weird to say I feel seen and cared for by them. I just don't think I have felt like this with any other business.

I used Nettle for four full cycles and was honestly surprised by how much it helped. My PMS symptoms—especially the fatigue, brain fog, and low mood—improved so much. I felt more balanced and clearer in the days before my period, which had not been the case for a long time. My pain also got better: I took less medication overall, and it worked faster when I did need it.
Generally, I think it might take more than four months to see the full effect, especially for pain, but what I did experience was already a big shift. The 90-day trial (and the extra time I was offered) made it feel safe to give it a proper try, and I really appreciated that.
The customer service is genuinely some of the best I have come across—kind, quick to reply, and clearly invested in helping people feel better.
So overall, I highly recommend this product - I really wish I had had this two years ago!

Nettle is very expensive and so I was skeptical that it would be worth it. I have used it for two cycles now. This is not a lot of data to compare, but both of these periods have been a lot easier to deal with than my usual ones - less pain, but more importantly, I didn't really experience much PMS/bad moods/mood swings in the preceeding days like I usually did. I am pleased with the purchase and would recommend. My only downside is that the app is a bit unclear about the protocols - it says "consistency is key" but I don't know if that means "use at exactly the same time every day" or just means "use it every day" for the five days before your period (in my case).

I have not received what I bought, nor got a refund.

I have been using Nettle for quite some time - more than half a year now. It has been hard with uneven cycle but I finally reached a place where I feel better most of the time. I was taking strong pain medicine for up to 5 days a month and it was damaging my liver. I couldn't sleep or work without it and the time between pills was excruciating. I am now not taking any medicine at all for my pain, it's way more manageable, I am more productive and don't feel mentally as bad. I wish it would solve other unfortunate symptoms that come during those days, but I at least feel like a person on those days!
I am especially happy for the support the team provides - any question, concern or idea is taken into consideration and I am happy to see so many improvements in the app.

I have used nettle for one full cycle and currently using for my 2nd cycle (period due in 2 days). So far, the difference has been unbelievable. I have endometriosis and PMDD, suspected ADHD but haven’t sought a diagnosis and don’t intend to. I have an 18 month old, cycle returned 6 months pp and I’m still breastfeeding. When my son turned a year old, my endo pain began to rear its ugly head again and was progressively getting worse every month (the pain was awful). Also PMDD so bad since having a baby, it was becoming completely debilitating and making parenting post ovulation horrendous. I had improvements using nettle from the word go, my ability to function and the reduction in brain fog is huge. I’m slightly “sharper” post ovulation with a more masculine cut throat attitude, but I feel more in control and at peace, in the type of way that makes you able to stay calm and not get so overwhelmed, be efficient and not overwhelmed. First period was significantly less painful, still took feminax but only once on one day :0!
2nd cycle, I was feeling so good I almost forgot to use the headband! But started feeling quite overwhelmed and foggy then realised I was due to use it the next day, pretty instant relief and feeling confident, in control and able to take on challenges. Fingers crossed this period also had reduced pain! Thanks so much

Three months ago, I was considering whether I should buy Nettle. Other users’ experiences were consistently positive, but I had already tried so many things that helped others but didn’t help me. I’ve suffered from severe menstrual pain and intense PMS symptoms—both physical and emotional—since I was 10 years old, so for the past 30 years. I had tried everything: supplements, teas, light therapy, electrotherapy, nutritional therapy, exercise, massages, essential oils, hormones. Nothing had worked.

When I discovered Nettle, I had pretty much given up hope that anything could still help me. But I gave it a try—hope dies last, as they say—especially since you can test the device for three months. And it helped me!!!

In the first month, I didn’t notice much of a difference yet. But in the second month, my PMS symptoms were reduced by 50%, and while I still had menstrual pain, it wasn’t as intense and lasted only one day instead of two. Then in the third month, my PMS symptoms were reduced by 80%! I still have menstrual pain, but the intensity has decreased again a bit.

I am truly so grateful that there are such wonderful people who developed this device and brought it to market to help people like me who have suffered so much for so long!! Thank you, thank you, thank you!

I'm using to see if it improves the symptoms of my recently diagnosed ADHD, which seem to have got much worse now that I am post-menopausal. It's a bit hard to tell but I am finding that I am generally more cheerful and that it improves my executive function ie getting stuff done, to some extent. I've been using it most days for a few months. It's a bit of a long term project for me and more research obviously needs to be done but

This device has helped me to feel like myself again, my symptoms are so much less severe than they used to be! I have been diagnosed with PMDD as a result of early perimenopause - the mood related symptoms were overwhelming, and I would often need to miss at least one day of work each cycle as a result. I'm four cycles in to using Nettle and will never look back. The changes were gradual and cumulative, but by the third cycle I felt as though my life had completely changed, I haven't had to take a day off work due to PMDD symptoms since the second cycle of using Nettle. Em is great! I emailed during my first cycle to ask about use for PMDD and she replied within a few hours with some very useful, tailored advice. I have been using Nettle for 20 consecutive days of my cycle and it has been nothing short of a miracle. The anxiety, feelings of intense grief and low mood which used to feel crippling towards the end of my cycle, are now muted and completely manageable - and don't last as long as they used to. HRT helped my symptoms to become cyclical, and Nettle has helped to reduce the psychological symptoms significantly.

It's worth every penny. I used Klarna pay in three and I'm so grateful for this as a payment option, as I would have struggled to pay the full amount up front. The 90 day money back guarantee makes this a no-brainer for anyone with severe pms, PMDD or perimenopause symptoms.

I am really impressed, I suffer from endometriosis and it has really helped. Also my PMDD symptom have been helped. The support and customer service has been great too.
