Mendi will help you sharpen your focus and develop more mental resilience. This validated neurocognitive training program uses a methodology that many athletes trust.

About Mendi.io

More precisely, Mendi is a soft headband that comes with non-intrusive sensors that bring your brain activity to life. All you have to do is place the headband on your forehead and start playing a specialized game. Then, Mendi starts measuring your oxygenated blood flow as a result of the neural activity in your prefrontal cortex.

Basically, your brain training journey is visualized with this game. You just make the ball rise and earn points, which indicates that there is an increase in your brain activity. On top of this, you can measure your progress, compare results, and track any improvements with the Mendi Score.

What to do if my Mendi discount code is not working

Problems with discount codes not working are nothing concerning, as applying promo codes comes with more issues than you may think. Below are a few tips and tricks in case your promo code isn’t applying correctly:

• Check for typing errors. If the Mendi promo code isn’t applied automatically, you might need to type it in manually. However, this can end in a mistake due to the possible typos you might make. Be very careful about whether you need to write in uppercase or lowercase letters, if there are any marks, or if you have missed something. To avoid all this, it’s best to just copy and paste it into the respective field.
• Check if the coupon applies to your purchase. Although Mendi offers the headband only, there might be a period when the product isn’t eligible for discount codes. That’s why you need to check this and ensure that you can save some dollars on your order.
• Check if the coupon code has expired. All coupon codes have expiration dates, meaning you can’t use them at any time. Due to this, it’s crucial to explore our Mendi discount code section carefully and check which promo codes are available and which have expired. Don’t worry. We’re constantly updating this page.
• Check whether you can combine the promo code with another promotion. Mendi offers some promo codes by itself. However, this doesn’t mean that you can combine the promotions they offer with the coupon codes on our page. First, find out if you can incorporate more discounts, and then try to use them.

Mendi warranty and returns policy

Mendi accepts returns because of its 60-day return policy. The only thing to keep in mind is not to exceed this period. Aside from this, you need to return the item in its original packaging and resellable condition.

However, you first need to contact the Mendi support team for your request. Then, you’ll get a return shipping label. After that, you will need to provide proof of the original purchase, which refers to the order number and the confirmation email. Once your return is approved, you need to pack the device with all the accessories, manuals, and packaging it came with.

Then, you should wait while the company inspects your return and see if your refund will be accepted. If yes, Mendi will issue a full refund of the initial fee (using your original payment method) with lower return shipping costs. However, processing the refund can take up to 10 days.

Mendi has a one-year warranty. This warranty covers all built-in defects and issues with not working well. However, it doesn’t cover damage that results from improper handling, unauthorized repairs, accidents, usage with unauthorized accessories, or any other reasons that compromise the device’s quality.

The best part is that Mendi might repair the product at no charge by using new or refurbished replacement parts or replace the device with a new or refurbished product.
