⚖️ Final Say
Read the summaries of what reviewers think about Mendi below.

“People praise customer service and the brand’s commitment to improving its customers’ well-being. Users report improvement in their stress and productivity levels. However, there are some users who are not sure they have seen any changes, highlighting how unique the experience is.”
“Looking back, I realize that my scientific approach to understanding stress ultimately led me to a more relaxed state. It’s lovely to see how Mendi’s technology can help others achieve similar results without going through the same trial-and-error process I did.”
“Considering the 30-day warranty and the lower price point compared to other neurofeedback devices, Mendi is a great option for anyone who is curious about brain training and wants to test it out before committing to a large expense.”
“The whole thing is an interesting and fun concept. I found Mendi to be a sleek looking wearable that works well. It’s also very simple to use and only takes a few minutes to go through the exercise. I look forward to trying out different games once they are made available as I am sure this will add to the appeal.”
“Based on customers’ reviews, online forums, and the scientific research surrounding the technology Mendi uses – it seems as though there might be some truth to its claims. It’s possible the device can help you with sleep, managing emotions, stress reduction, and focus. However, without FDA clearance and large-scale clinical trials, it’s impossible to say for certain the device is going to work the way you want it to. It’s best to consult a medical professional for personalized advice.”
“I was skeptical about Mendi and thought it might fall into that category. After a couple of weeks using Mendi, I am skeptical, but I am skeptical of my original skepticism. My golf game continues to be better, and I have no other way to explain that than Mendi. I plan to continue to use Mendi and see whether over the long run I see other positive changes.”
“Mendi is a functional near-infrared spectroscopy, or fNIRS device, that measures changes in blood oxygenation levels in the brain. The device connects to their app, where you are able to visualize your progress as you train your brain. This is done by the sensor of the Mendi device, which is placed on the forehead above the eyebrows, allowing for measurement of the neural activity of the prefrontal cortex, or PFC.”
“I really like the idea of providing an opportunity for people to ‘train their brain’ using phone app and a sensor type device to measure it, but I really don’t know how well Mendi accomplishes this.”
